Variational learning is a promising avenue that leverages classical optimization techniques to enhance quantum advantages on NISQ devices. However, most variational algorithms are circuit-model-based and encounter challenges when implemented on integrated photonic circuits, because they involve explicit decomposition of large quantum circuits into sequences of basic entangled gates, leading to an exponential decay of success probability due to the non-deterministic nature of photonic entangling gates. Here, we present a variational learning approach for designing quantum photonic circuits, which directly incorporates post-selection and elementary photonic elements into the training process. The complicated circuit is treated as a single nonlinear logical operator, and a unified design is discovered for it through variational learning. Engineering an integrated photonic chip with automated control, we adjust and optimize the internal parameters of the chip in real time for task-specific cost functions. We utilize a simple case of designing photonic circuits for a single ancilla CNOT gate with improved success rate to illustrate how our proposed approach works, and then apply the approach in the first demonstration of quantum stochastic simulation using integrated photonics. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2411.12417v1-abstract-full').style.display = 'none'; document.getElementById('2411.12417v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 19 November, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> November 2024. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2411.11008">arXiv:2411.11008</a> <span> [<a href="https://arxiv.org/pdf/2411.11008">pdf</a>, <a href="https://arxiv.org/format/2411.11008">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Plasma Physics">physics.plasm-ph</span> </div> </div> <p class="title is-5 mathjax"> Structure of weakly collisional shock waves of multicomponent plasmas inside hohlraums of indirect inertial confinement fusions </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Liang%2C+T">Tianyi Liang</a>, <a href="/search/physics?searchtype=author&query=Wu%2C+D">Dong Wu</a>, <a href="/search/physics?searchtype=author&query=Wang%2C+L">Lifeng Wang</a>, <a href="/search/physics?searchtype=author&query=Shan%2C+L">Lianqiang Shan</a>, <a href="/search/physics?searchtype=author&query=Yuan%2C+Z">Zongqiang Yuan</a>, <a href="/search/physics?searchtype=author&query=Cai%2C+H">Hongbo Cai</a>, <a href="/search/physics?searchtype=author&query=Gu%2C+Y">Yuqiu Gu</a>, <a href="/search/physics?searchtype=author&query=Sheng%2C+Z">Zhengmao Sheng</a>, <a href="/search/physics?searchtype=author&query=He%2C+X">Xiantu He</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2411.11008v1-abstract-short" style="display: inline;"> In laser-driven indirect inertial confinement fusion (ICF), a hohlraum--a cavity constructed from high-Z materials--serves the purpose of converting laser energy into thermal x-ray energy.

This process involves the interaction of low-density ablated plasmas, which can give rise to weakly collisional shock waves characterized by a Knudsen number $K_n$ on the order of 1. The Knudsen number serves as a metric for assessing the relative importance of collisional interactions. Preliminary experimental investigations and computational simulations have demonstrated that the kinetic effects associated with weakly collisional shock waves significantly impact the efficiency of the implosion process. Therefore, a comprehensive understanding of the physics underlying weakly collisional shock waves is essential. This research aims to explore the formation and fundamental structural properties of weakly collisional shock waves within a hohlraum, as well as the phenomena of ion mixing and ion separation in multicomponent plasmas. Weakly collisional shocks occupy a transition regime between collisional shock waves ($K_n \ll 1$) and collisionless shock waves ($K_n \gg 1$), thereby exhibiting both kinetic effects and hydrodynamic behavior. These shock waves are primarily governed by an electrostatic field, which facilitates significant electrostatic sheath acceleration and ion reflection acceleration. The differentiation of ions occurs due to the varying charge-to-mass ratios of different ion species in the presence of electrostatic field, resulting in the separation of ion densities, velocities, temperatures and concentrations. The presence of weakly collisional shock waves within the hohlraum is expected to affect the transition of laser energy and the overall efficiency of the implosion process. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2411.11008v1-abstract-full').style.display = 'none'; document.getElementById('2411.11008v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 17 November, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> November 2024. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2410.18817">arXiv:2410.18817</a> <span> [<a href="https://arxiv.org/pdf/2410.18817">pdf</a>, <a href="https://arxiv.org/format/2410.18817">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Phenomenology">hep-ph</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Accelerator Physics">physics.acc-ph</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> </div> </div> <p class="title is-5 mathjax"> Conceptual Design of the Muonium-to-Antimuonium Conversion Experiment (MACE) </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Bai%2C+A">Ai-Yu Bai</a>, <a href="/search/physics?searchtype=author&query=Cai%2C+H">Hanjie Cai</a>, <a href="/search/physics?searchtype=author&query=Chen%2C+C">Chang-Lin Chen</a>, <a href="/search/physics?searchtype=author&query=Chen%2C+S">Siyuan Chen</a>, <a href="/search/physics?searchtype=author&query=Chen%2C+X">Xurong Chen</a>, <a href="/search/physics?searchtype=author&query=Chen%2C+Y">Yu Chen</a>, <a href="/search/physics?searchtype=author&query=Cheng%2C+W">Weibin Cheng</a>, <a href="/search/physics?searchtype=author&query=Dai%2C+L">Ling-Yun Dai</a>, <a href="/search/physics?searchtype=author&query=Fan%2C+R">Rui-Rui Fan</a>, <a href="/search/physics?searchtype=author&query=Gong%2C+L">Li Gong</a>, <a href="/search/physics?searchtype=author&query=Guo%2C+Z">Zihao Guo</a>, <a href="/search/physics?searchtype=author&query=He%2C+Y">Yuan He</a>, <a href="/search/physics?searchtype=author&query=Hou%2C+Z">Zhilong Hou</a>, <a href="/search/physics?searchtype=author&query=Huang%2C+Y">Yinyuan Huang</a>, <a href="/search/physics?searchtype=author&query=Jia%2C+H">Huan Jia</a>, <a href="/search/physics?searchtype=author&query=Jiang%2C+H">Hao Jiang</a>, <a href="/search/physics?searchtype=author&query=Jing%2C+H">Han-Tao Jing</a>, <a href="/search/physics?searchtype=author&query=Kang%2C+X">Xiaoshen Kang</a>, <a href="/search/physics?searchtype=author&query=Li%2C+H">Hai-Bo Li</a>, <a href="/search/physics?searchtype=author&query=Li%2C+J">Jincheng Li</a>, <a href="/search/physics?searchtype=author&query=Li%2C+Y">Yang Li</a>, <a href="/search/physics?searchtype=author&query=Liu%2C+S">Shulin Liu</a>, <a href="/search/physics?searchtype=author&query=Lu%2C+G">Guihao Lu</a>, <a href="/search/physics?searchtype=author&query=Miao%2C+H">Han Miao</a>, <a href="/search/physics?searchtype=author&query=Ning%2C+Y">Yunsong Ning</a> , et al.

Using particle-in-cell simulations, we reveal a novel multi-beam collaborative mechanism of two-plasmon decay (TPD) and stimulated Raman scattering (SRS), and investigate the angular variations of hot electrons generated from this shared TPD-SRS (STS) instability driven collectively by dual laser beams with varying incident angles $胃_{in}$ ($24^\circ$ to $55^\circ$ at the incident plane) for typical ICF conditions. In the simulations with $胃_{in}\gtrsim44^\circ$, STS emerges as the dominant mechanism responsible for hot electron generation, leading to a wide angular distribution of hot electrons that exhibit both pronounced divergent and collimated components. The common Langmuir wave associated with STS plays a crucial role in accelerating both components.By properly modeling the STS common wave gains, we establish scaling relations between these gains and the energies of collimated and divergent hot electrons. These relations reveal that the divergent hot electrons are more sensitive to variations in gain compared to the collimated electrons. Additionally, the calculated gains qualitatively predict the asymmetry in hot electron angular distributions when the density gradients deviate from the bisector of the laser beams. Our findings offers insights for hot electron generation with multiple beams, potentially complementing previous experiments that underscore the critical role of overlapped intensity from symmetric beams within the same cone and the dominance of dual-beam coupling. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2410.12460v2-abstract-full').style.display = 'none'; document.getElementById('2410.12460v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 21 October, 2024; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 16 October, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> October 2024. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2410.07572">arXiv:2410.07572</a> <span> [<a href="https://arxiv.org/pdf/2410.07572">pdf</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Optics">physics.optics</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Signal Processing">eess.SP</span> </div> </div> <p class="title is-5 mathjax"> Edge-guided inverse design of digital metamaterials for ultra-high-capacity on-chip multi-dimensional interconnect </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Sun%2C+A">Aolong Sun</a>, <a href="/search/physics?searchtype=author&query=Xing%2C+S">Sizhe Xing</a>, <a href="/search/physics?searchtype=author&query=Deng%2C+X">Xuyu Deng</a>, <a href="/search/physics?searchtype=author&query=Shen%2C+R">Ruoyu Shen</a>, <a href="/search/physics?searchtype=author&query=Yan%2C+A">An Yan</a>, <a href="/search/physics?searchtype=author&query=Hu%2C+F">Fangchen Hu</a>, <a href="/search/physics?searchtype=author&query=Yuan%2C+Y">Yuqin Yuan</a>, <a href="/search/physics?searchtype=author&query=Dong%2C+B">Boyu Dong</a>, <a href="/search/physics?searchtype=author&query=Zhao%2C+J">Junhao Zhao</a>, <a href="/search/physics?searchtype=author&query=Huang%2C+O">Ouhan Huang</a>, <a href="/search/physics?searchtype=author&query=Li%2C+Z">Ziwei Li</a>, <a href="/search/physics?searchtype=author&query=Shi%2C+J">Jianyang Shi</a>, <a href="/search/physics?searchtype=author&query=Zhou%2C+Y">Yingjun Zhou</a>, <a href="/search/physics?searchtype=author&query=Shen%2C+C">Chao Shen</a>, <a href="/search/physics?searchtype=author&query=Zhao%2C+Y">Yiheng Zhao</a>, <a href="/search/physics?searchtype=author&query=Hong%2C+B">Bingzhou Hong</a>, <a href="/search/physics?searchtype=author&query=Chu%2C+W">Wei Chu</a>, <a href="/search/physics?searchtype=author&query=Zhang%2C+J">Junwen Zhang</a>, <a href="/search/physics?searchtype=author&query=Cai%2C+H">Haiwen Cai</a>, <a href="/search/physics?searchtype=author&query=Chi%2C+N">Nan Chi</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2410.07572v1-abstract-short" style="display: inline;"> The escalating demands of compute-intensive applications, including artificial intelligence, urgently necessitate the adoption of sophisticated optical on-chip interconnect technologies to overcome critical bottlenecks in scaling future computing systems.

This transition requires leveraging the inherent parallelism of wavelength and mode dimensions of light, complemented by high-order modulation formats, to significantly enhance data throughput. Here we experimentally demonstrate a novel synergy of these three dimensions, achieving multi-tens-of-terabits-per-second on-chip interconnects using ultra-broadband, multi-mode digital metamaterials. Employing a highly efficient edge-guided analog-and-digital optimization method, we inversely design foundry-compatible, robust, and multi-port digital metamaterials with an 8xhigher computational efficiency. Using a packaged five-mode multiplexing chip, we demonstrate a single-wavelength interconnect capacity of 1.62 Tbit s-1 and a record-setting multi-dimensional interconnect capacity of 38.2 Tbit s-1 across 5 modes and 88 wavelength channels. A theoretical analysis suggests that further system optimization can enable on-chip interconnects to reach sub-petabit-per-second data transmission rates. This study highlights the transformative potential of optical interconnect technologies to surmount the constraints of electronic links, thus setting the stage for next-generation datacenter and optical compute interconnects. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2410.07572v1-abstract-full').style.display = 'none'; document.getElementById('2410.07572v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 9 October, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> October 2024. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2409.17559">arXiv:2409.17559</a> <span> [<a href="https://arxiv.org/pdf/2409.17559">pdf</a>, <a href="https://arxiv.org/format/2409.17559">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Optics">physics.optics</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Quantum Physics">quant-ph</span> </div> </div> <p class="title is-5 mathjax"> Zak Phase Induced Topological Nonreciprocity </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Liu%2C+X">Xiao Liu</a>, <a href="/search/physics?searchtype=author&query=Wang%2C+J">Jiefei Wang</a>, <a href="/search/physics?searchtype=author&query=Mao%2C+R">Ruosong Mao</a>, <a href="/search/physics?searchtype=author&query=Hu%2C+H">Huizhu Hu</a>, <a href="/search/physics?searchtype=author&query=Zhu%2C+S">Shi-Yao Zhu</a>, <a href="/search/physics?searchtype=author&query=Xu%2C+X">Xingqi Xu</a>, <a href="/search/physics?searchtype=author&query=Cai%2C+H">Han Cai</a>, <a href="/search/physics?searchtype=author&query=Wang%2C+D">Da-Wei Wang</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2409.17559v1-abstract-short" style="display: inline;"> Topological physics provides novel insights for designing functional photonic devices, such as magnetic-free optical diodes, which are important in optical engineering and quantum information processing.

Past efforts mostly focus on the topological edge modes in two-dimensional (2D) photonic Chern lattices, which, however, require delicate fabrication and temporal modulation. In particular, the 1D nonreciprocal edge mode needs to be embedded in a 2D lattice, contradicting with the compactness of integrated photonics. To address these challenges, we investigate the optical nonreciprocity of the 1D Su-Schrieffer-Heeger (SSH) superradiance lattices in room-temperature atoms. The probe fields propagating in two opposite directions perceive two different SSH topological phases, which have different absorption spectra due to the interplay between the Zak phase and the thermal motion of atoms, resulting in optical nonreciprocity. Our findings reveal the relationship between 1D topological matter and optical nonreciprocity, simplifying the design of topologically resilient nonreciprocal devices. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2409.17559v1-abstract-full').style.display = 'none'; document.getElementById('2409.17559v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 26 September, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> September 2024. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">4 figures</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2408.14110">arXiv:2408.14110</a> <span> [<a href="https://arxiv.org/pdf/2408.14110">pdf</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Materials Science">cond-mat.mtrl-sci</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Optics">physics.optics</span> </div> </div> <p class="title is-5 mathjax"> Room-temperature Optically Detected Magnetic Resonance of Telecom Single Photon Emitters in GaN </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Eng%2C+J+J+H">John J.

To broaden their utility, operating at room temperature and emitting in the telecom wavelength range are desired, eliminating cryogenic requirements and leveraging existing optical fiber infrastructure for transmitting the quantum information. To that end, we report that telecom single photon emitters (SPEs) in gallium nitride (GaN) exhibit optically detected magnetic resonance (ODMR) at room temperature. The analysis of ODMR as a function of magnetic field orientation enables the determination of the orientation of the spin quantization axis with respect to the GaN crystalline lattice. The optical transitions dynamics are analyzed to gain further insight into the transition rates dominating ODMR. Our findings, coupled with GaN's mature fabrication technology, could facilitate the realization of scalable quantum technology. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2408.14110v1-abstract-full').style.display = 'none'; document.getElementById('2408.14110v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 26 August, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> August 2024. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2408.07348">arXiv:2408.07348</a> <span> [<a href="https://arxiv.org/pdf/2408.07348">pdf</a>, <a href="https://arxiv.org/format/2408.07348">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Optics">physics.optics</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Applied Physics">physics.app-ph</span> </div> </div> <p class="title is-5 mathjax"> From photon momentum transfer to acceleration sensing </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Yang%2C+J">Jianyu Yang</a>, <a href="/search/physics?searchtype=author&query=Li%2C+N">Nan Li</a>, <a href="/search/physics?searchtype=author&query=Pan%2C+Y">Yuyao Pan</a>, <a href="/search/physics?searchtype=author&query=Yang%2C+J">Jing Yang</a>, <a href="/search/physics?searchtype=author&query=Chen%2C+Z">Zhiming Chen</a>, <a href="/search/physics?searchtype=author&query=Cai%2C+H">Han Cai</a>, <a href="/search/physics?searchtype=author&query=Wang%2C+Y">Yuliang Wang</a>, <a href="/search/physics?searchtype=author&query=Han%2C+C">Chuankun Han</a>, <a href="/search/physics?searchtype=author&query=Chen%2C+X">Xingfan Chen</a>, <a href="/search/physics?searchtype=author&query=Liu%2C+C">Cheng Liu</a>, <a href="/search/physics?searchtype=author&query=Hu%2C+H">Huizhu Hu</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2408.07348v1-abstract-short" style="display: inline;"> As a typical application of photon momentum transfer, optical levitation systems are known for their ideal isolation from mechanical dissipation and thermal noise.

These characters offer extraordinary potential for acceleration precision sensing and have attracted extensive attention in both fundamental and applied physics. Although considerable improvements of optical levitation accelerometers has been reported, the dynamic testing of the sensing performance remains a crucial challenge before the utilization in practical application scenarios. In this work, we present a dual-beam optical levitation accelerometer and demonstrate the test with dynamic inputs for the first time. An acceleration sensing sensitivity of $0.1渭g$ and a measurement range of $ 1g$ are achieved. These advancements solidify the potential of optical levitation accelerometer for deployment in practical domains, including navigation, intelligent driving, and industrial automation, building a bridge between the laboratory systems and real-world applications. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2408.07348v1-abstract-full').style.display = 'none'; document.getElementById('2408.07348v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 14 August, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> August 2024. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">17 pages, 6 figures</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2408.06256">arXiv:2408.06256</a> <span> [<a href="https://arxiv.org/pdf/2408.06256">pdf</a>, <a href="https://arxiv.org/format/2408.06256">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Optics">physics.optics</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Quantum Physics">quant-ph</span> </div> </div> <p class="title is-5 mathjax"> Coupler enabled tunable dipole-dipole coupling between optically levitated nanoparticles </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Wu%2C+M">Mian Wu</a>, <a href="/search/physics?searchtype=author&query=Li%2C+N">Nan Li</a>, <a href="/search/physics?searchtype=author&query=Cai%2C+H">Han Cai</a>, <a href="/search/physics?searchtype=author&query=Hu%2C+H">Huizhu Hu</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2408.06256v2-abstract-short" style="display: inline;"> Multiple optically levitated particles in vacuum can exhibit electrostatic interactions, optical binding, and non-reciprocal light-induced dipole-dipole interactions, making them promising platforms for exploring mesoscopic entanglement and complex interactions.

However, in optical trap arrays, individually controlling the position and polarization of each trap is challenging, limiting the precise tuning of interactions between adjacent particles. This constraint hinders the study of complex interaction systems. In this work, we introduce a third nanoparticle as a coupler to two initially non-interacting nanoparticles, achieving tunable dipole-dipole coupling mediated by the third one. We investigated the effect of the particles' phases and positions on the interaction strength and demonstrated its broad tunability. Our method allows for precise control of interactions between any pair of adjacent particles in multi-particle systems, facilitating the further use of levitated nanoparticle arrays in macroscopic quantum mechanics and sensing. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2408.06256v2-abstract-full').style.display = 'none'; document.getElementById('2408.06256v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 16 August, 2024; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 12 August, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> August 2024. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2407.10613">arXiv:2407.10613</a> <span> [<a href="https://arxiv.org/pdf/2407.10613">pdf</a>, <a href="https://arxiv.org/format/2407.10613">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Plasma Physics">physics.plasm-ph</span> </div> </div> <p class="title is-5 mathjax"> Global destabilization of drift-tearing mode with coupling to discretized electron drift-wave instability </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Bao%2C+J">J.

Besides DTM, extra normal modes including EDW and SAW are coupled together and destabilized in different parameter regimes by considering resistivity in this system. The EVP approach is applied for solving the eigenstate spectra with the distribution of all unstable solutions. It is found that in the small EDD frequency (omega_*e) regime, DTM growth rate agrees well with local theory that is reduced with increasing omega_*e. However, when omega_*e exceeds a critical threshold omega_*crit, the strongly linear coupling between DTM and other discretized EDW instabilities happens so that the free energies from current and pressure channels can be released together and thus enhance the DTM, of which growth rate increases with increasing omega_*e and deviates from local theory results qualitatively. Correspondingly, a cross-scale mode structure forms with mixed polarization, namely, phi perturbation is dominated by electrostatic polarized short-wavelength oscillation as EDW instability character, and A_para perturbation remains typical tearing mode solution of Alfvenic polarized macroscopic structure. Within omega_*e > omega_*crit, the additional IDD causes phi oscillating structure to shift towards small density gradient domain, which cancels the extra drive from ion channel and thus DTM growth rate is insensitive to IDD frequency. Compared to EDD effects, the IDD effect alone with zero-omega_*e only leads to the stabilization of RTM that shows agreements between global simulation and local theory, which is no longer the condition for DTM regime. These results are useful for clarifying the DTM global properties with underlying physics mechanisms, which occurs in the regime of omega_*e >> gamma_c that is relevant to nowadays tokamak discharges with hot plasmas. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2407.10613v1-abstract-full').style.display = 'none'; document.getElementById('2407.10613v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 15 July, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> July 2024. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">23 pages, 15 figues</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2407.07651">arXiv:2407.07651</a> <span> [<a href="https://arxiv.org/pdf/2407.07651">pdf</a>, <a href="https://arxiv.org/format/2407.07651">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Data Analysis, Statistics and Probability">physics.data-an</span> </div> </div> <p class="title is-5 mathjax"> Study of the decay and production properties of $D_{s1}(2536)$ and $D_{s2}^*(2573)$ </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Ablikim%2C+M">M.

We are studying long Josephson junctions (long JJs), SFQs within them, and an SFQ detector, all intended for future ballistic logic gate experiments. Specifically, we launch low-energy SFQ into engineered long JJs made from an array of 80 JJs and connecting inductors. The component JJs have critical currents of only 7.5 uA such that the Josephson penetration depth is approximately 2.4 unit cells, and the SFQ's stationary energy in the LJJ is ~47 zJ. The circuit measured consisted of three components: an SFQ launcher, the LJJ, and an SFQ detector that uses JJ critical currents of only 15-20 uA. The circuit was measured in two environments: at 4.2 K in a helium dunk probe and 3.5~K in a cryogen-free refrigerator. According to calculations, the SFQ may traverse the LJJ ballistically, i.e., with a small change in velocity. Data show that SFQ detection events are synchronous with SFQ launch events in both setups. The jitter extracted from the launch and arrival times is predominantly attributed to the noise in the detector. This study shows that we can create and detect low-energy SFQs made from engineered LJJs, and the importance of jitter studies for future ballistic gate measurements. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2406.15671v2-abstract-full').style.display = 'none'; document.getElementById('2406.15671v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 16 December, 2024; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 21 June, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> June 2024. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2406.02494">arXiv:2406.02494</a> <span> [<a href="https://arxiv.org/pdf/2406.02494">pdf</a>, <a href="https://arxiv.org/format/2406.02494">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Quantum Physics">quant-ph</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Quantum Gases">cond-mat.quant-gas</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Optics">physics.optics</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1103/PhysRevLett.133.183403">10.1103/PhysRevLett.133.183403 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Velocity Scanning Tomography for Room-Temperature Quantum Simulation </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Wang%2C+J">Jiefei Wang</a>, <a href="/search/physics?searchtype=author&query=Mao%2C+R">Ruosong Mao</a>, <a href="/search/physics?searchtype=author&query=Xu%2C+X">Xingqi Xu</a>, <a href="/search/physics?searchtype=author&query=Lu%2C+Y">Yunzhou Lu</a>, <a href="/search/physics?searchtype=author&query=Dai%2C+J">Jianhao Dai</a>, <a href="/search/physics?searchtype=author&query=Liu%2C+X">Xiao Liu</a>, <a href="/search/physics?searchtype=author&query=Liu%2C+G">Gang-Qin Liu</a>, <a href="/search/physics?searchtype=author&query=Lu%2C+D">Dawei Lu</a>, <a href="/search/physics?searchtype=author&query=Hu%2C+H">Huizhu Hu</a>, <a href="/search/physics?searchtype=author&query=Zhu%2C+S">Shi-Yao Zhu</a>, <a href="/search/physics?searchtype=author&query=Cai%2C+H">Han Cai</a>, <a href="/search/physics?searchtype=author&query=Wang%2C+D">Da-Wei Wang</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2406.02494v1-abstract-short" style="display: inline;"> Quantum simulation offers an analog approach for exploring exotic quantum phenomena using controllable platforms, typically necessitating ultracold temperatures to maintain the quantum coherence.

Superradiance lattices (SLs) have been harnessed to simulate coherent topological physics at room temperature, but the thermal motion of atoms remains a notable challenge in accurately measuring the physical quantities. To overcome this obstacle, we invent and validate a velocity scanning tomography technique to discern the responses of atoms with different velocities, allowing cold-atom spectroscopic resolution within room-temperature SLs. By comparing absorption spectra with and without atoms moving at specific velocities, we can derive the Wannier-Stark ladders of the SL across various effective static electric fields, their strengths being proportional to the atomic velocities. We extract the Zak phase of the SL by monitoring the ladder frequency shift as a function of the atomic velocity, effectively demonstrating the topological winding of the energy bands. Our research signifies the feasibility of room-temperature quantum simulation and facilitates their applications in quantum information processing. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2406.02494v1-abstract-full').style.display = 'none'; document.getElementById('2406.02494v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 4 June, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> June 2024. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">6 pages, 4 figures</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2406.01635">arXiv:2406.01635</a> <span> [<a href="https://arxiv.org/pdf/2406.01635">pdf</a>, <a href="https://arxiv.org/format/2406.01635">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Data Analysis, Statistics and Probability">physics.data-an</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> </div> <p class="title is-5 mathjax"> SwdFold:A Reweighting and Unfolding method based on Optimal Transport Theory </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Pan%2C+C">Chu-Cheng Pan</a>, <a href="/search/physics?searchtype=author&query=Dong%2C+X">Xiang Dong</a>, <a href="/search/physics?searchtype=author&query=Sun%2C+Y">Yu-Chang Sun</a>, <a href="/search/physics?searchtype=author&query=Cheng%2C+A">Ao-Yan Cheng</a>, <a href="/search/physics?searchtype=author&query=Wang%2C+A">Ao-Bo Wang</a>, <a href="/search/physics?searchtype=author&query=Hu%2C+Y">Yu-Xuan Hu</a>, <a href="/search/physics?searchtype=author&query=Cai%2C+H">Hao Cai</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2406.01635v1-abstract-short" style="display: inline;"> High-energy physics experiments rely heavily on precise measurements of energy and momentum, yet face significant challenges due to detector limitations, calibration errors, and the intrinsic nature of particle interactions.

Traditional unfolding techniques have been employed to correct for these distortions, yet they often suffer from model dependency and stability issues. We present a novel method, SwdFold, which utilizes the principles of optimal transport to provide a robust, model-independent framework to estimate the probability density ratio for data unfolding. It not only unfold the toy experimental event by reweighted simulated data distributions closely with true distributions but also maintains the integrity of physical features across various observables. We can expect it can enable more reliable predictions and comprehensive analyses as a high precision reweighting and unfolding tool in high-energy physics. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2406.01635v1-abstract-full').style.display = 'none'; document.getElementById('2406.01635v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 2 June, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> June 2024. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2405.17860">arXiv:2405.17860</a> <span> [<a href="https://arxiv.org/pdf/2405.17860">pdf</a>, <a href="https://arxiv.org/format/2405.17860">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1088/1674-1137/ad83aa">10.1088/1674-1137/ad83aa <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Prediction of Energy Resolution in the JUNO Experiment </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=JUNO+Collaboration"> JUNO Collaboration</a>, <a href="/search/physics?searchtype=author&query=Abusleme%2C+A">Angel Abusleme</a>, <a href="/search/physics?searchtype=author&query=Adam%2C+T">Thomas Adam</a>, <a href="/search/physics?searchtype=author&query=Adamowicz%2C+K">Kai Adamowicz</a>, <a href="/search/physics?searchtype=author&query=Ahmad%2C+S">Shakeel Ahmad</a>, <a href="/search/physics?searchtype=author&query=Ahmed%2C+R">Rizwan Ahmed</a>, <a href="/search/physics?searchtype=author&query=Aiello%2C+S">Sebastiano Aiello</a>, <a href="/search/physics?searchtype=author&query=An%2C+F">Fengpeng An</a>, <a href="/search/physics?searchtype=author&query=An%2C+Q">Qi An</a>, <a href="/search/physics?searchtype=author&query=Andronico%2C+G">Giuseppe Andronico</a>, <a href="/search/physics?searchtype=author&query=Anfimov%2C+N">Nikolay Anfimov</a>, <a href="/search/physics?searchtype=author&query=Antonelli%2C+V">Vito Antonelli</a>, <a href="/search/physics?searchtype=author&query=Antoshkina%2C+T">Tatiana Antoshkina</a>, <a href="/search/physics?searchtype=author&query=de+Andr%C3%A9%2C+J+P+A+M">Jo茫o Pedro Athayde Marcondes de Andr茅</a>, <a href="/search/physics?searchtype=author&query=Auguste%2C+D">Didier Auguste</a>, <a href="/search/physics?searchtype=author&query=Bai%2C+W">Weidong Bai</a>, <a href="/search/physics?searchtype=author&query=Balashov%2C+N">Nikita Balashov</a>, <a href="/search/physics?searchtype=author&query=Baldini%2C+W">Wander Baldini</a>, <a href="/search/physics?searchtype=author&query=Barresi%2C+A">Andrea Barresi</a>, <a href="/search/physics?searchtype=author&query=Basilico%2C+D">Davide Basilico</a>, <a href="/search/physics?searchtype=author&query=Baussan%2C+E">Eric Baussan</a>, <a href="/search/physics?searchtype=author&query=Bellato%2C+M">Marco Bellato</a>, <a href="/search/physics?searchtype=author&query=Beretta%2C+M">Marco Beretta</a>, <a href="/search/physics?searchtype=author&query=Bergnoli%2C+A">Antonio Bergnoli</a>, <a href="/search/physics?searchtype=author&query=Bick%2C+D">Daniel Bick</a> , et al.

The determination of neutrino mass ordering in JUNO requires an exceptional energy resolution better than 3\% at 1~MeV. To achieve this ambitious goal, significant efforts have been undertaken in the design and production of the key components of the JUNO detector. Various factors affecting the detection of inverse beta decay signals have an impact on the energy resolution, extending beyond the statistical fluctuations of the detected number of photons, such as the properties of the liquid scintillator, performance of photomultiplier tubes, and the energy reconstruction algorithm. To account for these effects, a full JUNO simulation and reconstruction approach is employed. This enables the modeling of all relevant effects and the evaluation of associated inputs to accurately estimate the energy resolution. The results of study reveal an energy resolution of 2.95\% at 1~MeV. Furthermore, this study assesses the contribution of major effects to the overall energy resolution budget. This analysis serves as a reference for interpreting future measurements of energy resolution during JUNO data collection. Moreover, it provides a guideline for comprehending the energy resolution characteristics of liquid scintillator-based detectors. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2405.17860v2-abstract-full').style.display = 'none'; document.getElementById('2405.17860v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 9 January, 2025; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 28 May, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> May 2024. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Chinese Phys.

To mitigate the pandemic's impacts, different regions implemented various policies to contain COVID-19 and residents showed diverse responses. These human responses in turn shaped the uneven spatial-temporal spread of COVID-19. Consequently, the human-pandemic interaction is complex, dynamic, and interconnected. Delineating the reciprocal effects between human society and the pandemic is imperative for mitigating risks from future epidemics. Geospatial big data acquired through mobile applications and sensor networks have facilitated near-real-time tracking and assessment of human responses to the pandemic, enabling a surge in researching human-pandemic interactions. However, these investigations involve inconsistent data sources, human activity indicators, relationship detection models, and analysis methods, leading to a fragmented understanding of human-pandemic dynamics. To assess the current state of human-pandemic interactions research, we conducted a synthesis study based on 67 selected publications between March 2020 and January 2023. We extracted key information from each article across six categories, e.g., research area and time, data, methodological framework, and results and conclusions. Results reveal that regression models were predominant in relationship detection, featured in 67.16% of papers. Only two papers employed spatial-temporal models, notably underrepresented in the existing literature. Studies examining the effects of policies and human mobility on the pandemic's health impacts were the most prevalent, each comprising 12 articles (17.91%). Only 3 papers (4.48%) delved into bidirectional interactions between human responses and the COVID-19 spread. These findings shed light on the need for future research to spatially and temporally model the long-term, bidirectional causal relationships within human-pandemic systems. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2404.10013v1-abstract-full').style.display = 'none'; document.getElementById('2404.10013v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 12 April, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> April 2024. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2404.03681">arXiv:2404.03681</a> <span> [<a href="https://arxiv.org/pdf/2404.03681">pdf</a>, <a href="https://arxiv.org/format/2404.03681">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> </div> <p class="title is-5 mathjax"> Muon beamtest results of high-density glass scintillator tiles </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Du%2C+D">Dejing Du</a>, <a href="/search/physics?searchtype=author&query=Liu%2C+Y">Yong Liu</a>, <a href="/search/physics?searchtype=author&query=Cai%2C+H">Hua Cai</a>, <a href="/search/physics?searchtype=author&query=Chen%2C+D">Danping Chen</a>, <a href="/search/physics?searchtype=author&query=Hua%2C+Z">Zhehao Hua</a>, <a href="/search/physics?searchtype=author&query=Han%2C+J">Jifeng Han</a>, <a href="/search/physics?searchtype=author&query=Han%2C+J">Jifeng Han</a>, <a href="/search/physics?searchtype=author&query=Qi%2C+B">Baohua Qi</a>, <a href="/search/physics?searchtype=author&query=Qian%2C+S">Sen Qian</a>, <a href="/search/physics?searchtype=author&query=Ren%2C+J">Jing Ren</a>, <a href="/search/physics?searchtype=author&query=Sun%2C+X">Xinyuan Sun</a>, <a href="/search/physics?searchtype=author&query=Sun%2C+X">Xinyuan Sun</a>, <a href="/search/physics?searchtype=author&query=Yang%2C+D">Dong Yang</a>, <a href="/search/physics?searchtype=author&query=Yin%2C+S">Shenghua Yin</a>, <a href="/search/physics?searchtype=author&query=Zhang%2C+M">Minghui Zhang</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2404.03681v2-abstract-short" style="display: inline;"> To achieve the physics goal of precisely measure the Higgs, Z, W bosons and the top quark, future electron-positron colliders require that their detector system has excellent jet energy resolution.

One feasible technical option is the high granular calorimetery based on the particle flow algorithm (PFA). A new high-granularity hadronic calorimeter with glass scintillator tiles (GSHCAL) has been proposed, which focus on the significant improvement of hadronic energy resolution with a notable increase of the energy sampling fraction by using high-density glass scintillator tiles. The minimum ionizing particle (MIP) response of a glass scintillator tile is crucial to the hadronic calorimeter, so a dedicated beamtest setup was developed for testing the first batch of large-size glass scintillators. The maximum MIP response of the first batch of glass scintillator tiles can reach up to 107 p.e./MIP, which essentially meets the design requirements of the CEPC GSHCAL. An optical simulation model of a single glass scintillator tile has been established, and the simulation results are consistent with the beamtest results. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2404.03681v2-abstract-full').style.display = 'none'; document.getElementById('2404.03681v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 9 May, 2024; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 31 March, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> April 2024. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2403.09225">arXiv:2403.09225</a> <span> [<a href="https://arxiv.org/pdf/2403.09225">pdf</a>, <a href="https://arxiv.org/format/2403.09225">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Computational Physics">physics.comp-ph</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> </div> <p class="title is-5 mathjax"> PWACG: Partial Wave Analysis Code Generator supporting Newton-conjugate gradient method </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Dong%2C+X">Xiang Dong</a>, <a href="/search/physics?searchtype=author&query=Sun%2C+Y">Yu-Chang Sun</a>, <a href="/search/physics?searchtype=author&query=Pan%2C+C">Chu-Cheng Pan</a>, <a href="/search/physics?searchtype=author&query=Cheng%2C+A">Ao-Yan Cheng</a>, <a href="/search/physics?searchtype=author&query=Wang%2C+A">Ao-Bo Wang</a>, <a href="/search/physics?searchtype=author&query=Cai%2C+H">Hao Cai</a>, <a href="/search/physics?searchtype=author&query=Zhu%2C+K">Kai Zhu</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2403.09225v1-abstract-short" style="display: inline;"> This paper introduces a novel Partial Wave Analysis Code Generator (PWACG) that automatically generates high-performance partial wave analysis codes.

However, in conventional LF communication systems, their antenna size is required to be inversely proportional to the wavelength, so that their mobility and flexibility are greatly limited. Here we introduce a novel prototype of LF receiving antennas based on optically levitated nanoparticles, which overcomes the size-frequency limitation to reduce the antenna size to the hundred-nanometer scale. These charged particles are extremely sensitive to external electric field as mechanical resonators, and their resonant frequencies are adjustable. The effectiveness of these antennas was experimentally demonstrated by using the frequency shift keying (2FSK) modulation scheme. The experimental results indicate a correlation between error rate and factors such as transmission rate, signal strength, and vacuum degree with a signal strength of approximately 0.1V/m and a bit error rate below 0.1%. This advancement in leveraging levitated particle mechanical resonators (LPMRs) as LF antennas marks a significant stride in long-distance communication technology. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2402.10907v1-abstract-full').style.display = 'none'; document.getElementById('2402.10907v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 10 January, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> February 2024. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2402.03361">arXiv:2402.03361</a> <span> [<a href="https://arxiv.org/pdf/2402.03361">pdf</a>, <a href="https://arxiv.org/format/2402.03361">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Soft Condensed Matter">cond-mat.soft</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Fluid Dynamics">physics.flu-dyn</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1063/5.0193321">10.1063/5.0193321 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Vanishing in Fractal Space: Thermal Melting and Hydrodynamic Collapse </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Phan%2C+T+V">Trung V.

We apply our findings on the fractal environments crucial for plant growth: natural soils. We focus on the transport phenomenon of cavity shrinkage in incompressible fluid, conducting a numerical study beyond the inviscid limit. We reveal how a minimal collapsing time can emerge through a non-trivial coupling between the fluid viscosity and the surface fractal dimension. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2402.03361v2-abstract-full').style.display = 'none'; document.getElementById('2402.03361v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 20 February, 2024; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 29 January, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> February 2024. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Physics of Fluids 36, 033107 (2024) </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2401.10995">arXiv:2401.10995</a> <span> [<a href="https://arxiv.org/pdf/2401.10995">pdf</a>, <a href="https://arxiv.org/format/2401.10995">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Computation and Language">cs.CL</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Medical Physics">physics.med-ph</span> </div> </div> <p class="title is-5 mathjax"> The Radiation Oncology NLP Database </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Liu%2C+Z">Zhengliang Liu</a>, <a href="/search/physics?searchtype=author&query=Holmes%2C+J">Jason Holmes</a>, <a href="/search/physics?searchtype=author&query=Liao%2C+W">Wenxiong Liao</a>, <a href="/search/physics?searchtype=author&query=Liu%2C+C">Chenbin Liu</a>, <a href="/search/physics?searchtype=author&query=Zhang%2C+L">Lian Zhang</a>, <a href="/search/physics?searchtype=author&query=Feng%2C+H">Hongying Feng</a>, <a href="/search/physics?searchtype=author&query=Wang%2C+P">Peilong Wang</a>, <a href="/search/physics?searchtype=author&query=Elahi%2C+M+A">Muhammad Ali Elahi</a>, <a href="/search/physics?searchtype=author&query=Cai%2C+H">Hongmin Cai</a>, <a href="/search/physics?searchtype=author&query=Sun%2C+L">Lichao Sun</a>, <a href="/search/physics?searchtype=author&query=Li%2C+Q">Quanzheng Li</a>, <a href="/search/physics?searchtype=author&query=Li%2C+X">Xiang Li</a>, <a href="/search/physics?searchtype=author&query=Liu%2C+T">Tianming Liu</a>, <a href="/search/physics?searchtype=author&query=Shen%2C+J">Jiajian Shen</a>, <a href="/search/physics?searchtype=author&query=Liu%2C+W">Wei Liu</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2401.10995v1-abstract-short" style="display: inline;"> We present the Radiation Oncology NLP Database (ROND), the first dedicated Natural Language Processing (NLP) dataset for radiation oncology, an important medical specialty that has received limited attention from the NLP community in the past.

With the advent of Artificial General Intelligence (AGI), there is an increasing need for specialized datasets and benchmarks to facilitate research and development. ROND is specifically designed to address this gap in the domain of radiation oncology, a field that offers many opportunities for NLP exploration. It encompasses various NLP tasks including Logic Reasoning, Text Classification, Named Entity Recognition (NER), Question Answering (QA), Text Summarization, and Patient-Clinician Conversations, each with a distinct focus on radiation oncology concepts and application cases. In addition, we have developed an instruction-tuning dataset consisting of over 20k instruction pairs (based on ROND) and trained a large language model, CancerChat. This serves to demonstrate the potential of instruction-tuning large language models within a highly-specialized medical domain. The evaluation results in this study could serve as baseline results for future research. ROND aims to stimulate advancements in radiation oncology and clinical NLP by offering a platform for testing and improving algorithms and models in a domain-specific context. The ROND dataset is a joint effort of multiple U.S. health institutions. The data is available at https://github.com/zl-liu/Radiation-Oncology-NLP-Database. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2401.10995v1-abstract-full').style.display = 'none'; document.getElementById('2401.10995v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 19 January, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> January 2024. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">10 pages, 7 figures, 6 tables</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2401.08794">arXiv:2401.08794</a> <span> [<a href="https://arxiv.org/pdf/2401.08794">pdf</a>, <a href="https://arxiv.org/format/2401.08794">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Plasma Physics">physics.plasm-ph</span> </div> </div> <p class="title is-5 mathjax"> Bohm-like Neoclassical Transport in Highly Collisional Toroidal Plasmas with High Density Gradients </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Xiao%2C+J">Jianyuan Xiao</a>, <a href="/search/physics?searchtype=author&query=Cai%2C+H">Huishan Cai</a>, <a href="/search/physics?searchtype=author&query=Liu%2C+J">Jian Liu</a>, <a href="/search/physics?searchtype=author&query=Yu%2C+Z">Zhi Yu</a>, <a href="/search/physics?searchtype=author&query=Zheng%2C+Y">Yifeng Zheng</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2401.08794v1-abstract-short" style="display: inline;"> Conventional neoclassical theory in the Pfirsch-Schl眉ter regime fails to accurately model collision-induced transport in toroidal plasmas with high density gradients.

While in most scenarios, sensors with a fixed thermal conductivity inevitably mismatch the analogous parameter of the medium being measured, thus causing the distortion and inaccurate detection of original temperature fields. Despite recent efforts on addressing the parameter-mismatch issue, all current solutions are constrained to a fixed working medium whereas a more universal sensor should function in a variety of scenes. Here, we report a dynamic thermal sensor capable of highly accurate measurements in diverse working environments. Remarkably, thanks to the highly tunable thermal conductivity of the expanded-plane structure, this sensor works effect on background mediums with a wide range of conductivity. Such a development greatly enhances the robustness and adaptability of thermal sensors, setting a solid foundation for applications in multi-physical sensing scenarios. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2401.03364v1-abstract-full').style.display = 'none'; document.getElementById('2401.03364v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 6 January, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> January 2024. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2310.17897">arXiv:2310.17897</a> <span> [<a href="https://arxiv.org/pdf/2310.17897">pdf</a>, <a href="https://arxiv.org/format/2310.17897">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Computational Physics">physics.comp-ph</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> </div> <p class="title is-5 mathjax"> Event Generation and Consistence Test for Physics with Sliced Wasserstein Distance </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Pan%2C+C">Chu-Cheng Pan</a>, <a href="/search/physics?searchtype=author&query=Dong%2C+X">Xiang Dong</a>, <a href="/search/physics?searchtype=author&query=Sun%2C+Y">Yu-Chang Sun</a>, <a href="/search/physics?searchtype=author&query=Cheng%2C+A">Ao-Yan Cheng</a>, <a href="/search/physics?searchtype=author&query=Wang%2C+A">Ao-Bo Wang</a>, <a href="/search/physics?searchtype=author&query=Hu%2C+Y">Yu-Xuan Hu</a>, <a href="/search/physics?searchtype=author&query=Cai%2C+H">Hao Cai</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2310.17897v1-abstract-short" style="display: inline;"> In the field of modern high-energy physics research, there is a growing emphasis on utilizing deep learning techniques to optimize event simulation, thereby expanding the statistical sample size for more accurate physical analysis.

Traditional simulation methods often encounter challenges when dealing with complex physical processes and high-dimensional data distributions, resulting in slow performance. To overcome these limitations, we propose a solution based on deep learning with the sliced Wasserstein distance as the loss function. Our method shows its ability on high precision and large-scale simulations, and demonstrates its effectiveness in handling complex physical processes. By employing an advanced transformer learning architecture, we initiate the learning process from a Monte Carlo sample, and generate high-dimensional data while preserving all original distribution features. The generated data samples have passed the consistence test, that is developed to calculate the confidence of the high-dimentional distributions of the generated data samples through permutation tests. This fast simulation strategy, enabled by deep learning, holds significant potential not only for increasing sample sizes and reducing statistical uncertainties but also for applications in numerical integration, which is crucial in partial wave analysis, high-precision sample checks, and other related fields. It opens up new possibilities for improving event simulation in high-energy physics research. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2310.17897v1-abstract-full').style.display = 'none'; document.getElementById('2310.17897v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 27 October, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> October 2023. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2309.11075">arXiv:2309.11075</a> <span> [<a href="https://arxiv.org/pdf/2309.11075">pdf</a>, <a href="https://arxiv.org/format/2309.11075">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Plasma Physics">physics.plasm-ph</span> </div> </div> <p class="title is-5 mathjax"> Large-scale Kinetic Simulations of Colliding Plasmas within a Hohlraum of Indirect Drive Inertial Confinement Fusions </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Liang%2C+T">Tianyi Liang</a>, <a href="/search/physics?searchtype=author&query=Wu%2C+D">Dong Wu</a>, <a href="/search/physics?searchtype=author&query=Ning%2C+X">Xiaochuan Ning</a>, <a href="/search/physics?searchtype=author&query=Shan%2C+L">Lianqiang Shan</a>, <a href="/search/physics?searchtype=author&query=Yuan%2C+Z">Zongqiang Yuan</a>, <a href="/search/physics?searchtype=author&query=Cai%2C+H">Hongbo Cai</a>, <a href="/search/physics?searchtype=author&query=Sheng%2C+Z">Zhengmao Sheng</a>, <a href="/search/physics?searchtype=author&query=He%2C+X">Xiantu He</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2309.11075v1-abstract-short" style="display: inline;"> The National Ignition Facility has recently achieved successful burning plasma and ignition using the inertial confinement fusion (ICF) approach.

However, there are still many fundamental physics phenomena that are not well understood, including the kinetic processes in the hohlraum. Shan et al. [Phys. Rev. Lett, 120, 195001, 2018] utilized the energy spectra of neutrons to investigate the kinetic colliding plasma in a hohlraum of indirect drive ICF. However, due to the typical large spatial-temporal scales, this experiment could not be well simulated by using available codes at that time. Utilizing our advanced high-order implicit PIC code, LAPINS, we were able to successfully reproduce the experiment on a large scale of both spatial and temporal dimensions, in which the original computational scale was increased by approximately 7 to 8 orders of magnitude. When gold plasmas expand into deuterium plasmas, a kinetic shock is generated and propagates within deuterium plasmas. Simulations allow us to observe the entire progression of a strong shock wave, including its initial formation and steady propagation. Although both electrons and gold ions are collisional (on a small scale compared to the shock wave), deuterium ions seem to be collisionless. This is because a quasi-monoenergetic spectrum of deuterium ions can be generated by reflecting ions from the shock front, which then leads to the production of neutrons with unusual broadening due to beam-target nuclear reactions. This work displays an unprecedented kinetic analysis of an existing experiment, shedding light on the mechanisms behind shock wave formation. It also serves as a reference for benchmark simulations of upcoming new simulation codes and may be relevant for future research on mixtures and entropy increments at plasma interfaces. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2309.11075v1-abstract-full').style.display = 'none'; document.getElementById('2309.11075v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 20 September, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> September 2023. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2309.01520">arXiv:2309.01520</a> <span> [<a href="https://arxiv.org/pdf/2309.01520">pdf</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Accelerator Physics">physics.acc-ph</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> </div> </div> <p class="title is-5 mathjax"> Towards a high-intensity muon source at CiADS </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Cai%2C+H">Han-Jie Cai</a>, <a href="/search/physics?searchtype=author&query=He%2C+Y">Yuan He</a>, <a href="/search/physics?searchtype=author&query=Liu%2C+S">Shuhui Liu</a>, <a href="/search/physics?searchtype=author&query=Jia%2C+H">Huan Jia</a>, <a href="/search/physics?searchtype=author&query=Qin%2C+Y">Yuanshuai Qin</a>, <a href="/search/physics?searchtype=author&query=Wang%2C+Z">Zhijun Wang</a>, <a href="/search/physics?searchtype=author&query=Wang%2C+F">Fengfeng Wang</a>, <a href="/search/physics?searchtype=author&query=Zhao%2C+L">Lixia Zhao</a>, <a href="/search/physics?searchtype=author&query=Pu%2C+N">Neng Pu</a>, <a href="/search/physics?searchtype=author&query=Niu%2C+J">Jianwei Niu</a>, <a href="/search/physics?searchtype=author&query=Chen%2C+L">Liangwen Chen</a>, <a href="/search/physics?searchtype=author&query=Sun%2C+Z">Zhiyu Sun</a>, <a href="/search/physics?searchtype=author&query=Zhao%2C+H">Hongwei Zhao</a>, <a href="/search/physics?searchtype=author&query=Zhan%2C+W">Wenlong Zhan</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2309.01520v1-abstract-short" style="display: inline;"> The proposal of a high-intensity muon source driven by the CiADS linac, which has the potential to be one of the state-of-the-art facilities, is presented in this paper.

We propose a new method, SpreadDetect, that estimates both the source coordinate and the initial timepoint of change in such a setting. We prove that under appropriate conditions, the SpreadDetect algorithm consistently estimates both the source coordinate and the timepoint of change and that the minimal signal size detectable by the algorithm is minimax optimal. The practical utility of the algorithm is demonstrated through numerical experiments and a COVID-19 real dataset. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2306.10475v1-abstract-full').style.display = 'none'; document.getElementById('2306.10475v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 18 June, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> June 2023. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">26 pages,3 figures, 2 tables</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2305.14895">arXiv:2305.14895</a> <span> [<a href="https://arxiv.org/pdf/2305.14895">pdf</a>, <a href="https://arxiv.org/format/2305.14895">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Instrumentation and Methods for Astrophysics">astro-ph.IM</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1088/1674-4527/acd593">10.1088/1674-4527/acd593 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> The Lobster Eye Imager for Astronomy Onboard the SATech-01 Satellite </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Ling%2C+Z+X">Z.

In this paper, we introduce the design and on-ground test results of the LEIA instrument. Using state-of-the-art Micro-Pore Optics (MPO), a wide field-of-view (FoV) of 346 square degrees (18.6 degrees * 18.6 degrees) of the X-ray imager is realized. An optical assembly composed of 36 MPO chips is used to focus incident X-ray photons, and four large-format complementary metal-oxide semiconductor (CMOS) sensors, each of 6 cm * 6 cm, are used as the focal plane detectors. The instrument has an angular resolution of 4 - 8 arcmin (in FWHM) for the central focal spot of the point spread function, and an effective area of 2 - 3 cm2 at 1 keV in essentially all the directions within the field of view. The detection passband is 0.5 - 4 keV in the soft X-rays and the sensitivity is 2 - 3 * 10-11 erg s-1 cm-2 (about 1 mini-Crab) at 1,000 second observation. The total weight of LEIA is 56 kg and the power is 85 W. The satellite, with a design lifetime of 2 years, operates in a Sun-synchronous orbit of 500 km with an orbital period of 95 minutes. LEIA is paving the way for future missions by verifying in flight the technologies of both novel focusing imaging optics and CMOS sensors for X-ray observation, and by optimizing the working setups of the instrumental parameters. In addition, LEIA is able to carry out scientific observations to find new transients and to monitor known sources in the soft X-ray band, albeit limited useful observing time available. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2305.14895v1-abstract-full').style.display = 'none'; document.getElementById('2305.14895v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 24 May, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> May 2023. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">Accepted by RAA</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2305.14184">arXiv:2305.14184</a> <span> [<a href="https://arxiv.org/pdf/2305.14184">pdf</a>, <a href="https://arxiv.org/format/2305.14184">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Applied Physics">physics.app-ph</span> </div> </div> <p class="title is-5 mathjax"> High-Temperature Superconductor Quantum Flux Parametron for Energy-Efficient Logic </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Cai%2C+H">Han Cai</a>, <a href="/search/physics?searchtype=author&query=LeFebvre%2C+J+C">Jay C.

This has inspired a race to develop alternative low-power computational technologies. A new adiabatic configuration of a decades-old superconducting digital logic device has darted into the lead called quantum flux parametrons (QFP). QFP operate with dissipation so low that they seemingly violate the laws of thermodynamics. In just a short span of time, they have gone from simple single NOT gates to complex processors containing thousands of gates. They are fabricated from elemental niobium superconductors cooled to just a few degrees above absolute zero. However, their efficiency is so great that for large high-performance computers with several gates, the energy savings are immense. For smaller computational platforms QFPs from high-temperature superconductors (high-Tc) are highly desirable. In this work, we take the first steps towards this goal with the demonstration of a high-T C QFP shift register. Our device is fabricated using focused helium ion beam lithography where the material is modified with an ion beam at the nanoscale to directly pattern these circuits into a high-T C thin film. We validate the correct logical operation at 25 K, over 6 times higher than niobium devices with an estimated bit energy of 0.1 attoJoule at 10 GHz. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2305.14184v1-abstract-full').style.display = 'none'; document.getElementById('2305.14184v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 23 May, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> May 2023. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2305.10515">arXiv:2305.10515</a> <span> [<a href="https://arxiv.org/pdf/2305.10515">pdf</a>, <a href="https://arxiv.org/format/2305.10515">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1088/1748-0221/19/05/P05065">10.1088/1748-0221/19/05/P05065 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> The LHCb upgrade I </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=LHCb+collaboration"> LHCb collaboration</a>, <a href="/search/physics?searchtype=author&query=Aaij%2C+R">R.

Readout of all detectors into an all-software trigger is central to the new design, facilitating the reconstruction of events at the maximum LHC interaction rate, and their selection in real time. The experiment's tracking system has been completely upgraded with a new pixel vertex detector, a silicon tracker upstream of the dipole magnet and three scintillating fibre tracking stations downstream of the magnet. The whole photon detection system of the RICH detectors has been renewed and the readout electronics of the calorimeter and muon systems have been fully overhauled. The first stage of the all-software trigger is implemented on a GPU farm. The output of the trigger provides a combination of totally reconstructed physics objects, such as tracks and vertices, ready for final analysis, and of entire events which need further offline reprocessing. This scheme required a complete revision of the computing model and rewriting of the experiment's software. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2305.10515v2-abstract-full').style.display = 'none'; document.getElementById('2305.10515v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 10 September, 2024; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 17 May, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> May 2023. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">All figures and tables, along with any supplementary material and additional information, are available at http://lhcbproject.web.cern.ch/lhcbproject/Publications/LHCbProjectPublic/LHCb-DP-2022-002.html (LHCb public pages)</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Report number:</span> LHCb-DP-2022-002 </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> JINST 19 (2024) P05065 </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2305.05906">arXiv:2305.05906</a> <span> [<a href="https://arxiv.org/pdf/2305.05906">pdf</a>, <a href="https://arxiv.org/format/2305.05906">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Optics">physics.optics</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Mesoscale and Nanoscale Physics">cond-mat.mes-hall</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1038/s41467-024-45580-w">10.1038/s41467-024-45580-w <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Realization of all-band-flat photonic lattices </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Yang%2C+J">Jing Yang</a>, <a href="/search/physics?searchtype=author&query=Li%2C+Y">Yuanzhen Li</a>, <a href="/search/physics?searchtype=author&query=Yang%2C+Y">Yumeng Yang</a>, <a href="/search/physics?searchtype=author&query=Xie%2C+X">Xinrong Xie</a>, <a href="/search/physics?searchtype=author&query=Zhang%2C+Z">Zijian Zhang</a>, <a href="/search/physics?searchtype=author&query=Yuan%2C+J">Jiale Yuan</a>, <a href="/search/physics?searchtype=author&query=Cai%2C+H">Han Cai</a>, <a href="/search/physics?searchtype=author&query=Wang%2C+D">Da-Wei Wang</a>, <a href="/search/physics?searchtype=author&query=Gao%2C+F">Fei Gao</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2305.05906v2-abstract-short" style="display: inline;"> Flatbands play an important role in correlated quantum matter and have novel applications in photonic lattices.

Synthetic magnetic fields and destructive interference in lattices are traditionally used to obtain flatbands. However, such methods can only obtain a few flatbands with most bands remaining dispersive. Here we realize all-band-flat photonic lattices of an arbitrary size by precisely controlling the coupling strengths between lattice sites to mimic those in Fock-state lattices. This allows us to go beyond the perturbative regime of strain engineering and group all eigenmodes in flatbands, which simultaneously achieves high band flatness and large usable bandwidth. We map out the distribution of each flatband in the lattices and selectively excite the eigenmodes with different chiralities. Our method paves a new way in controlling band structure and topology of photonic lattices. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2305.05906v2-abstract-full').style.display = 'none'; document.getElementById('2305.05906v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 5 January, 2024; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 10 May, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> May 2023. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Nat.

However, social media use varies across demographics, with younger users being more prevalent compared to older populations. This difference introduces biases in data representativeness, and analysis based on social media without proper adjustment will lead to overlooking the voices of digitally marginalized communities and inaccurate estimations. This study explores solutions to pinpoint and alleviate the demographic biases in social media analysis through a case study estimating the public sentiment about COVID-19 using Twitter data. We analyzed the pandemic-related Twitter data in the U.S. during 2020-2021 to (1) elucidate the uneven social media usage among demographic groups and the disparities of their sentiments toward COVID-19, (2) construct an adjusted public sentiment measurement based on social media, the Sentiment Adjusted by Demographics (SAD) index, to evaluate the spatiotemporal varying public sentiment toward COVID-19. The results show higher proportions of female and adolescent Twitter users expressing negative emotions to COVID-19. The SAD index unveils that the public sentiment toward COVID-19 was most negative in January and February 2020 and most positive in April 2020. Vermont and Wyoming were the most positive and negative states toward COVID-19. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2304.06120v2-abstract-full').style.display = 'none'; document.getElementById('2304.06120v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 2 August, 2023; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 16 March, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> April 2023. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2303.15790">arXiv:2303.15790</a> <span> [<a href="https://arxiv.org/pdf/2303.15790">pdf</a>, <a href="https://arxiv.org/format/2303.15790">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Phenomenology">hep-ph</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1007/s11467-023-1333-z">10.1007/s11467-023-1333-z <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> STCF Conceptual Design Report: Volume 1 -- Physics & Detector </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Achasov%2C+M">M.

The STCF will produce a data sample about a factor of 100 larger than that by the present $蟿$-Charm factory -- the BEPCII, providing a unique platform for exploring the asymmetry of matter-antimatter (charge-parity violation), in-depth studies of the internal structure of hadrons and the nature of non-perturbative strong interactions, as well as searching for exotic hadrons and physics beyond the Standard Model. The STCF project in China is under development with an extensive R\&D program.

This muon tracker will help to evaluate the contribution of the cosmogenic background to the signal. The Top Tracker is located above JUNO's water Cherenkov Detector and Central Detector, covering about 60% of the surface above them. The JUNO Top Tracker is constituted by the decommissioned OPERA experiment Target Tracker modules. The technology used consists in walls of two planes of plastic scintillator strips, one per transverse direction. Wavelength shifting fibres collect the light signal emitted by the scintillator strips and guide it to both ends where it is read by multianode photomultiplier tubes. Compared to the OPERA Target Tracker, the JUNO Top Tracker uses new electronics able to cope with the high rate produced by the high rock radioactivity compared to the one in Gran Sasso underground laboratory. This paper will present the new electronics and mechanical structure developed for the Top Tracker of JUNO along with its expected performance based on the current detector simulation. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2303.05172v1-abstract-full').style.display = 'none'; document.getElementById('2303.05172v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 9 March, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> March 2023. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">20 pages</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Nucl.Instrum.Meth.A 1057 (2023) 168680 </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2303.03910">arXiv:2303.03910</a> <span> [<a href="https://arxiv.org/pdf/2303.03910">pdf</a>, <a href="https://arxiv.org/format/2303.03910">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> </div> </div> <p class="title is-5 mathjax"> JUNO sensitivity to $^7$Be, $pep$, and CNO solar neutrinos </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Abusleme%2C+A">Angel Abusleme</a>, <a href="/search/physics?searchtype=author&query=Adam%2C+T">Thomas Adam</a>, <a href="/search/physics?searchtype=author&query=Ahmad%2C+S">Shakeel Ahmad</a>, <a href="/search/physics?searchtype=author&query=Ahmed%2C+R">Rizwan Ahmed</a>, <a href="/search/physics?searchtype=author&query=Aiello%2C+S">Sebastiano Aiello</a>, <a href="/search/physics?searchtype=author&query=Akram%2C+M">Muhammad Akram</a>, <a href="/search/physics?searchtype=author&query=Aleem%2C+A">Abid Aleem</a>, <a href="/search/physics?searchtype=author&query=Alexandros%2C+T">Tsagkarakis Alexandros</a>, <a href="/search/physics?searchtype=author&query=An%2C+F">Fengpeng An</a>, <a href="/search/physics?searchtype=author&query=An%2C+Q">Qi An</a>, <a href="/search/physics?searchtype=author&query=Andronico%2C+G">Giuseppe Andronico</a>, <a href="/search/physics?searchtype=author&query=Anfimov%2C+N">Nikolay Anfimov</a>, <a href="/search/physics?searchtype=author&query=Antonelli%2C+V">Vito Antonelli</a>, <a href="/search/physics?searchtype=author&query=Antoshkina%2C+T">Tatiana Antoshkina</a>, <a href="/search/physics?searchtype=author&query=Asavapibhop%2C+B">Burin Asavapibhop</a>, <a href="/search/physics?searchtype=author&query=de+Andr%C3%A9%2C+J+P+A+M">Jo茫o Pedro Athayde Marcondes de Andr茅</a>, <a href="/search/physics?searchtype=author&query=Auguste%2C+D">Didier Auguste</a>, <a href="/search/physics?searchtype=author&query=Bai%2C+W">Weidong Bai</a>, <a href="/search/physics?searchtype=author&query=Balashov%2C+N">Nikita Balashov</a>, <a href="/search/physics?searchtype=author&query=Baldini%2C+W">Wander Baldini</a>, <a href="/search/physics?searchtype=author&query=Barresi%2C+A">Andrea Barresi</a>, <a href="/search/physics?searchtype=author&query=Basilico%2C+D">Davide Basilico</a>, <a href="/search/physics?searchtype=author&query=Baussan%2C+E">Eric Baussan</a>, <a href="/search/physics?searchtype=author&query=Bellato%2C+M">Marco Bellato</a>, <a href="/search/physics?searchtype=author&query=Beretta%2C+M">Marco Beretta</a> , et al.

JUNO's large target mass and excellent energy resolution are prerequisites for reaching unprecedented levels of precision. In this paper, we provide estimation of the JUNO sensitivity to 7Be, pep, and CNO solar neutrinos that can be obtained via a spectral analysis above the 0.45 MeV threshold. This study is performed assuming different scenarios of the liquid scintillator radiopurity, ranging from the most opti mistic one corresponding to the radiopurity levels obtained by the Borexino experiment, up to the minimum requirements needed to perform the neutrino mass ordering determination with reactor antineutrinos - the main goal of JUNO. Our study shows that in most scenarios, JUNO will be able to improve the current best measurements on 7Be, pep, and CNO solar neutrino fluxes. We also perform a study on the JUNO capability to detect periodical time variations in the solar neutrino flux, such as the day-night modulation induced by neutrino flavor regeneration in Earth, and the modulations induced by temperature changes driven by helioseismic waves. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2303.03910v1-abstract-full').style.display = 'none'; document.getElementById('2303.03910v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 7 March, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> March 2023. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2212.04898">arXiv:2212.04898</a> <span> [<a href="https://arxiv.org/pdf/2212.04898">pdf</a>, <a href="https://arxiv.org/format/2212.04898">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Quantum Gases">cond-mat.quant-gas</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Optics">physics.optics</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Quantum Physics">quant-ph</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1103/PhysRevLett.129.273603">10.1103/PhysRevLett.129.273603 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Floquet superradiance lattices in thermal atoms </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Xu%2C+X">Xingqi Xu</a>, <a href="/search/physics?searchtype=author&query=Wang%2C+J">Jiefei Wang</a>, <a href="/search/physics?searchtype=author&query=Dai%2C+J">Jianhao Dai</a>, <a href="/search/physics?searchtype=author&query=Mao%2C+R">Ruosong Mao</a>, <a href="/search/physics?searchtype=author&query=Cai%2C+H">Han Cai</a>, <a href="/search/physics?searchtype=author&query=Zhu%2C+S">Shi-Yao Zhu</a>, <a href="/search/physics?searchtype=author&query=Wang%2C+D">Da-Wei Wang</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2212.04898v1-abstract-short" style="display: inline;"> Floquet modulation has been widely used in optical lattices for coherent control of quantum gases, in particular for synthesizing artificial gauge fields and simulating topological matters.

However, such modulation induces heating which can overwhelm the signal of quantum dynamics in ultracold atoms. Here we report that the thermal motion, instead of being a noise source, provides a new control knob in Floquet-modulated superradiance lattices, which are momentum-space tight-binding lattices of collectively excited states of atoms. The Doppler shifts combined with Floquet modulation provide effective forces along arbitrary directions in a lattice in frequency and momentum dimensions. Dynamic localization, dynamic delocalization and chiral edge currents can be simultaneously observed from a single transport spectrum of superradiance lattices in thermal atoms. Our work paves a way for simulating Floquet topological matters in room-temperature atoms and facilitates their applications in photonic devices. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2212.04898v1-abstract-full').style.display = 'none'; document.getElementById('2212.04898v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 9 December, 2022; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> December 2022. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">7 pages, 4 figures</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Phys.

Classical degrees of freedom such as polarizations and wavevectors are routinely used to synthesize topological light modes. Beyond the classical regime, inherent quantum nature of light gives birth to a wealth of fundamentally distinct topological states, which offer topological protection in quantum information processing. Here we implement such experiments on topological states of quantized light in a superconducting circuit, on which three resonators are tunably coupled to a gmon qubit. We construct one and two-dimensional Fock-state lattices where topological transport of zero-energy states, strain induced pseudo-Landau levels, valley Hall effect and Haldane chiral edge currents are demonstrated. Our study extends the topological states of light to the quantum regime, bridges topological phases of condensed matter physics with circuit quantum electrodynamics, and offers a new freedom in controlling the quantum states of multiple resonators. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2208.03452v1-abstract-full').style.display = 'none'; document.getElementById('2208.03452v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 6 August, 2022; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> August 2022. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">9 pages, 6 figures</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Science 378, 966 (2022) </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2205.08830">arXiv:2205.08830</a> <span> [<a href="https://arxiv.org/pdf/2205.08830">pdf</a>, <a href="https://arxiv.org/format/2205.08830">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Astrophysical Phenomena">astro-ph.HE</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Phenomenology">hep-ph</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1088/1475-7516/2022/10/033">10.1088/1475-7516/2022/10/033 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Prospects for Detecting the Diffuse Supernova Neutrino Background with JUNO </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=JUNO+Collaboration"> JUNO Collaboration</a>, <a href="/search/physics?searchtype=author&query=Abusleme%2C+A">Angel Abusleme</a>, <a href="/search/physics?searchtype=author&query=Adam%2C+T">Thomas Adam</a>, <a href="/search/physics?searchtype=author&query=Ahmad%2C+S">Shakeel Ahmad</a>, <a href="/search/physics?searchtype=author&query=Ahmed%2C+R">Rizwan Ahmed</a>, <a href="/search/physics?searchtype=author&query=Aiello%2C+S">Sebastiano Aiello</a>, <a href="/search/physics?searchtype=author&query=Akram%2C+M">Muhammad Akram</a>, <a href="/search/physics?searchtype=author&query=An%2C+F">Fengpeng An</a>, <a href="/search/physics?searchtype=author&query=An%2C+Q">Qi An</a>, <a href="/search/physics?searchtype=author&query=Andronico%2C+G">Giuseppe Andronico</a>, <a href="/search/physics?searchtype=author&query=Anfimov%2C+N">Nikolay Anfimov</a>, <a href="/search/physics?searchtype=author&query=Antonelli%2C+V">Vito Antonelli</a>, <a href="/search/physics?searchtype=author&query=Antoshkina%2C+T">Tatiana Antoshkina</a>, <a href="/search/physics?searchtype=author&query=Asavapibhop%2C+B">Burin Asavapibhop</a>, <a href="/search/physics?searchtype=author&query=de+Andr%C3%A9%2C+J+P+A+M">Jo茫o Pedro Athayde Marcondes de Andr茅</a>, <a href="/search/physics?searchtype=author&query=Auguste%2C+D">Didier Auguste</a>, <a href="/search/physics?searchtype=author&query=Balashov%2C+N">Nikita Balashov</a>, <a href="/search/physics?searchtype=author&query=Baldini%2C+W">Wander Baldini</a>, <a href="/search/physics?searchtype=author&query=Barresi%2C+A">Andrea Barresi</a>, <a href="/search/physics?searchtype=author&query=Basilico%2C+D">Davide Basilico</a>, <a href="/search/physics?searchtype=author&query=Baussan%2C+E">Eric Baussan</a>, <a href="/search/physics?searchtype=author&query=Bellato%2C+M">Marco Bellato</a>, <a href="/search/physics?searchtype=author&query=Bergnoli%2C+A">Antonio Bergnoli</a>, <a href="/search/physics?searchtype=author&query=Birkenfeld%2C+T">Thilo Birkenfeld</a>, <a href="/search/physics?searchtype=author&query=Blin%2C+S">Sylvie Blin</a> , et al.

We employ the latest information on the DSNB flux predictions, and investigate in detail the background and its reduction for the DSNB search at JUNO. The atmospheric neutrino induced neutral current (NC) background turns out to be the most critical background, whose uncertainty is carefully evaluated from both the spread of model predictions and an envisaged \textit{in situ} measurement. We also make a careful study on the background suppression with the pulse shape discrimination (PSD) and triple coincidence (TC) cuts. With latest DSNB signal predictions, more realistic background evaluation and PSD efficiency optimization, and additional TC cut, JUNO can reach the significance of 3$蟽$ for 3 years of data taking, and achieve better than 5$蟽$ after 10 years for a reference DSNB model. In the pessimistic scenario of non-observation, JUNO would strongly improve the limits and exclude a significant region of the model parameter space. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2205.08830v2-abstract-full').style.display = 'none'; document.getElementById('2205.08830v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 13 October, 2022; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 18 May, 2022; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> May 2022. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">29 pages, 11 figures, final published version in JCAP</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> JCAP 10 (2022) 033 </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2205.08629">arXiv:2205.08629</a> <span> [<a href="https://arxiv.org/pdf/2205.08629">pdf</a>, <a href="https://arxiv.org/format/2205.08629">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1140/epjc/s10052-022-11002-8">10.1140/epjc/s10052-022-11002-8 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Mass Testing and Characterization of 20-inch PMTs for JUNO </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Abusleme%2C+A">Angel Abusleme</a>, <a href="/search/physics?searchtype=author&query=Adam%2C+T">Thomas Adam</a>, <a href="/search/physics?searchtype=author&query=Ahmad%2C+S">Shakeel Ahmad</a>, <a href="/search/physics?searchtype=author&query=Ahmed%2C+R">Rizwan Ahmed</a>, <a href="/search/physics?searchtype=author&query=Aiello%2C+S">Sebastiano Aiello</a>, <a href="/search/physics?searchtype=author&query=Akram%2C+M">Muhammad Akram</a>, <a href="/search/physics?searchtype=author&query=Aleem%2C+A">Abid Aleem</a>, <a href="/search/physics?searchtype=author&query=Alexandros%2C+T">Tsagkarakis Alexandros</a>, <a href="/search/physics?searchtype=author&query=An%2C+F">Fengpeng An</a>, <a href="/search/physics?searchtype=author&query=An%2C+Q">Qi An</a>, <a href="/search/physics?searchtype=author&query=Andronico%2C+G">Giuseppe Andronico</a>, <a href="/search/physics?searchtype=author&query=Anfimov%2C+N">Nikolay Anfimov</a>, <a href="/search/physics?searchtype=author&query=Antonelli%2C+V">Vito Antonelli</a>, <a href="/search/physics?searchtype=author&query=Antoshkina%2C+T">Tatiana Antoshkina</a>, <a href="/search/physics?searchtype=author&query=Asavapibhop%2C+B">Burin Asavapibhop</a>, <a href="/search/physics?searchtype=author&query=de+Andre%2C+J+P+A+M">Joao Pedro Athayde Marcondes de Andre</a>, <a href="/search/physics?searchtype=author&query=Auguste%2C+D">Didier Auguste</a>, <a href="/search/physics?searchtype=author&query=Bai%2C+W">Weidong Bai</a>, <a href="/search/physics?searchtype=author&query=Balashov%2C+N">Nikita Balashov</a>, <a href="/search/physics?searchtype=author&query=Baldini%2C+W">Wander Baldini</a>, <a href="/search/physics?searchtype=author&query=Barresi%2C+A">Andrea Barresi</a>, <a href="/search/physics?searchtype=author&query=Basilico%2C+D">Davide Basilico</a>, <a href="/search/physics?searchtype=author&query=Baussan%2C+E">Eric Baussan</a>, <a href="/search/physics?searchtype=author&query=Bellato%2C+M">Marco Bellato</a>, <a href="/search/physics?searchtype=author&query=Bergnoli%2C+A">Antonio Bergnoli</a> , et al.

Its key feature is an excellent energy resolution of at least 3 % at 1 MeV, for which its instruments need to meet a certain quality and thus have to be fully characterized. More than 20,000 20-inch PMTs have been received and assessed by JUNO after a detailed testing program which began in 2017 and elapsed for about four years. Based on this mass characterization and a set of specific requirements, a good quality of all accepted PMTs could be ascertained. This paper presents the performed testing procedure with the designed testing systems as well as the statistical characteristics of all 20-inch PMTs intended to be used in the JUNO experiment, covering more than fifteen performance parameters including the photocathode uniformity. This constitutes the largest sample of 20-inch PMTs ever produced and studied in detail to date, i.e. 15,000 of the newly developed 20-inch MCP-PMTs from Northern Night Vision Technology Co. (NNVT) and 5,000 of dynode PMTs from Hamamatsu Photonics K.

However, the intensive training process of neural networks for molecules with ever-increasing complexity has resulted in exponential growth in computation cost, leading to long simulation time and high energy consumption. Photonic chip technology offers an alternative platform for implementing neural networks with faster data processing and lower energy usage compared to digital computers. Photonics technology is naturally capable of implementing complex-valued neural networks at no additional hardware cost. Here, we demonstrate the capability of photonic neural networks for predicting the quantum mechanical properties of molecules. To the best of our knowledge, this work is the first to harness photonic technology for machine learning applications in computational chemistry and molecular sciences, such as drug discovery and materials design. We further show that multiple properties can be learned simultaneously in a photonic chip via a multi-task regression learning algorithm, which is also the first of its kind as well, as most previous works focus on implementing a network in the classification task. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2203.02285v2-abstract-full').style.display = 'none'; document.getElementById('2203.02285v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 25 December, 2022; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 2 March, 2022; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> March 2022. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2202.07384">arXiv:2202.07384</a> <span> [<a href="https://arxiv.org/pdf/2202.07384">pdf</a>, <a href="https://arxiv.org/format/2202.07384">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1088/1748-0221/17/05/P05024">10.1088/1748-0221/17/05/P05024 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> The Phase-I Trigger Readout Electronics Upgrade of the ATLAS Liquid Argon Calorimeters </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Aad%2C+G">G.

The new system, installed during the second Large Hadron Collider Long Shutdown, increases the trigger readout granularity by up to a factor of ten as well as its precision and range. Consequently, the background rejection at trigger level is improved through enhanced filtering algorithms utilizing the additional information for topological discrimination of electromagnetic and hadronic shower shapes. This paper presents the final designs of the new electronic elements, their custom electronic devices, the procedures used to validate their proper functioning, and the performance achieved during the commissioning of this system. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2202.07384v2-abstract-full').style.display = 'none'; document.getElementById('2202.07384v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 16 May, 2022; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 15 February, 2022; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> February 2022. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">56 pages, 41 figures, 6 tables</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> 2022 JINST 17 P05024 </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2111.12378">arXiv:2111.12378</a> <span> [<a href="https://arxiv.org/pdf/2111.12378">pdf</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Quantum Gases">cond-mat.quant-gas</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Optics">physics.optics</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Quantum Physics">quant-ph</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1038/s41377-022-00990-7">10.1038/s41377-022-00990-7 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Measuring Zak phase in room-temperature atoms </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Mao%2C+R">Ruosong Mao</a>, <a href="/search/physics?searchtype=author&query=Xu%2C+X">Xingqi Xu</a>, <a href="/search/physics?searchtype=author&query=Wang%2C+J">Jiefei Wang</a>, <a href="/search/physics?searchtype=author&query=Xu%2C+C">Chenran Xu</a>, <a href="/search/physics?searchtype=author&query=Qian%2C+G">Gewei Qian</a>, <a href="/search/physics?searchtype=author&query=Cai%2C+H">Han Cai</a>, <a href="/search/physics?searchtype=author&query=Zhu%2C+S">Shi-Yao Zhu</a>, <a href="/search/physics?searchtype=author&query=Wang%2C+D">Da-Wei Wang</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2111.12378v2-abstract-short" style="display: inline;"> Cold atoms provide a flexible platform for synthesizing and characterizing topolog-ical matter, where geometric phases play a central role.

However, cold atoms are intrinsically prone to thermal noise, which can overwhelm the topological response and hamper promised applications. On the other hand, geometric phases also de-termine the energy spectra of particles subjected to a static force, based on the po-larization relation between Wannier-Stark ladders and geometric Zak phases. By exploiting this relation, we develop a method to extract geometric phases from en-ergy spectra of room-temperature superradiance lattices, which are momentum-space lattices of timed Dicke states. In such momentum-space lattices the thermal motion of atoms, instead of being a source of noise, provides effective forces which lead to spectroscopic signatures of the Zak phases. We measure Zak phases direct-ly from the anti-crossings between Wannier-Stark ladders in the Doppler-broadened absorption spectra of superradiance lattices. Our approach paves the way of measuring topological invariants and developing their applications in room-temperature atoms. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2111.12378v2-abstract-full').style.display = 'none'; document.getElementById('2111.12378v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 12 October, 2022; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 24 November, 2021; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> November 2021. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">28 pages, 5 figures</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Light: Science & Applications (2022) 11:291 </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2111.06582">arXiv:2111.06582</a> <span> [<a href="https://arxiv.org/pdf/2111.06582">pdf</a>, <a href="https://arxiv.org/ps/2111.06582">ps</a>, <a href="https://arxiv.org/format/2111.06582">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Atomic Physics">physics.atom-ph</span> </div> </div> <p class="title is-5 mathjax"> Sensitivity improvement of Rydberg atom-based microwave sensing via electromagnetically induced transparency </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Cai%2C+M+H">M.

It can be used as susceptible atom-based microwave communication antennas where the carrier wave usually works exactly resonant to the transition between a pair of adjacent Rydberg states with large electric dipole moment. A technique of superheterodyne with a strong on-resonant local microwave oscillator is employed to induce considerable Autler-Townes splitting where the antennas has a highest dynamic response to another weak target signal microwave carrier. To further improve the sensitivity of atomic antenna in communication, we detune the carrier microwave frequency off resonance forming an asymmetrically optical splitting and fix the coupling laser frequency at the shoulder of the stronger one, and optimize the local field strength simultaneously. It gives a sensitivity of 12.50(04) $\rm{nVcm^{-1}\cdot Hz^{-1/2}}$. Its enhancement mechanism of sensitivity is also proved by a theoretical simulation. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2111.06582v1-abstract-full').style.display = 'none'; document.getElementById('2111.06582v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 12 November, 2021; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> November 2021. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2111.05494">arXiv:2111.05494</a> <span> </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Optics">physics.optics</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Mesoscale and Nanoscale Physics">cond-mat.mes-hall</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Materials Science">cond-mat.mtrl-sci</span> </div> </div> <p class="title is-5 mathjax"> Type-printable photodetector arrays for multichannel meta-infrared imaging </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Guo%2C+J">Junxiong Guo</a>, <a href="/search/physics?searchtype=author&query=Gu%2C+S">Shuyi Gu</a>, <a href="/search/physics?searchtype=author&query=Lin%2C+L">Lin Lin</a>, <a href="/search/physics?searchtype=author&query=Liu%2C+Y">Yu Liu</a>, <a href="/search/physics?searchtype=author&query=Cai%2C+J">Ji Cai</a>, <a href="/search/physics?searchtype=author&query=Cai%2C+H">Hongyi Cai</a>, <a href="/search/physics?searchtype=author&query=Tian%2C+Y">Yu Tian</a>, <a href="/search/physics?searchtype=author&query=Zhang%2C+Y">Yuelin Zhang</a>, <a href="/search/physics?searchtype=author&query=Zhang%2C+Q">Qinghua Zhang</a>, <a href="/search/physics?searchtype=author&query=Liu%2C+Z">Ze Liu</a>, <a href="/search/physics?searchtype=author&query=Zhang%2C+Y">Yafei Zhang</a>, <a href="/search/physics?searchtype=author&query=Zhang%2C+X">Xiaosheng Zhang</a>, <a href="/search/physics?searchtype=author&query=Lin%2C+Y">Yuan Lin</a>, <a href="/search/physics?searchtype=author&query=Huang%2C+W">Wen Huang</a>, <a href="/search/physics?searchtype=author&query=Gu%2C+L">Lin Gu</a>, <a href="/search/physics?searchtype=author&query=Zhang%2C+J">Jinxing Zhang</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2111.05494v7-abstract-short" style="display: inline;"> Multichannel meta-imaging, inspired by the parallel-processing capability of neuromorphic computing, offers significant advancements in resolution enhancement and edge discrimination in imaging systems, extending even into the mid- to far-infrared spectrum.

Currently typical multichannel infrared imaging systems consist of separating optical gratings or merging multi-cameras, which require complex circuit design and heavy power consumption, hindering the implementation of advanced human-eye-like imagers. Here, we present a novel approach for printable graphene plasmonic photodetector arrays driven by a ferroelectric superdomain for multichannel meta-infrared imaging with enhanced edge discrimination. The fabricated photodetectors exhibited multiple spectral responses with zero-bias operation by directly rescaling the ferroelectric superdomain instead of reconstructing the separated gratings. We also demonstrated enhanced and faster shape classification (98.1%) and edge detection (98.2%) using our multichannel infrared images compared with single-channel detectors. Our proof-of-concept photodetector arrays simplify multichannel infrared imaging systems and hold great potential for applications in efficient edge detection in human-brain-type machine vision. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2111.05494v7-abstract-full').style.display = 'none'; document.getElementById('2111.05494v7-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 6 May, 2024; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 9 November, 2021; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> November 2021. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">Some specific concerns should be addressed or updated. e.g. Fig. 3d</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2111.03446">arXiv:2111.03446</a> <span> [<a href="https://arxiv.org/pdf/2111.03446">pdf</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Physics and Society">physics.soc-ph</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Social and Information Networks">cs.SI</span> </div> </div> <p class="title is-5 mathjax"> Revealing the Global Linguistic and Geographical Disparities of Public Awareness to Covid-19 Outbreak through Social Media </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Lin%2C+B">Binbin Lin</a>, <a href="/search/physics?searchtype=author&query=Zou%2C+L">Lei Zou</a>, <a href="/search/physics?searchtype=author&query=Duffield%2C+N">Nick Duffield</a>, <a href="/search/physics?searchtype=author&query=Mostafavi%2C+A">Ali Mostafavi</a>, <a href="/search/physics?searchtype=author&query=Cai%2C+H">Heng Cai</a>, <a href="/search/physics?searchtype=author&query=Zhou%2C+B">Bing Zhou</a>, <a href="/search/physics?searchtype=author&query=Tao%2C+J">Jian Tao</a>, <a href="/search/physics?searchtype=author&query=Yang%2C+M">Mingzheng Yang</a>, <a href="/search/physics?searchtype=author&query=Mandal%2C+D">Debayan Mandal</a>, <a href="/search/physics?searchtype=author&query=Abedin%2C+J">Joynal Abedin</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2111.03446v3-abstract-short" style="display: inline;"> The Covid-19 has presented an unprecedented challenge to public health worldwide.

However, residents in different countries showed diverse levels of Covid-19 awareness during the outbreak and suffered from uneven health impacts. This study analyzed the global Twitter data from January 1st to June 30th, 2020, seeking to answer two research questions. What are the linguistic and geographical disparities of public awareness in the Covid-19 outbreak period reflected on social media? Can the changing pandemic awareness predict the Covid-19 outbreak? We established a Twitter data mining framework calculating the Ratio index to quantify and track the awareness. The lag correlations between awareness and health impacts were examined at global and country levels. Results show that users presenting the highest Covid-19 awareness were mainly those tweeting in the official languages of India and Bangladesh. Asian countries showed more significant disparities in awareness than European countries, and awareness in the eastern part of Europe was higher than in central Europe. Finally, the Ratio index could accurately predict global mortality rate, global case fatality ratio, and country-level mortality rate, with 21-30, 35-42, and 17 leading days, respectively. This study yields timely insights into social media use in understanding human behaviors for public health research. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2111.03446v3-abstract-full').style.display = 'none'; document.getElementById('2111.03446v3-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 8 November, 2021; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 29 October, 2021; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> November 2021. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2110.14219">arXiv:2110.14219</a> <span> [<a href="https://arxiv.org/pdf/2110.14219">pdf</a>, <a href="https://arxiv.org/format/2110.14219">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Plasma Physics">physics.plasm-ph</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1063/5.0060593">10.1063/5.0060593 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Gyrokinetic simulations of electric current generation in ion temperature gradient driven turbulence </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Chen%2C+X">Xiang Chen</a>, <a href="/search/physics?searchtype=author&query=Lu%2C+Z">Zhixin Lu</a>, <a href="/search/physics?searchtype=author&query=Cai%2C+H">Huishan Cai</a>, <a href="/search/physics?searchtype=author&query=Ye%2C+L">Lei Ye</a>, <a href="/search/physics?searchtype=author&query=Chen%2C+Y">Yang Chen</a>, <a href="/search/physics?searchtype=author&query=Gao%2C+B">Baofeng Gao</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2110.14219v1-abstract-short" style="display: inline;"> Gyrokinetic simulations in the collisionless limit demonstrate the physical mechanisms and the amplitude of the current driven by turbulence.

The so-called "spontaneous" current is featured with large local magnitude near the rational surfaces. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2110.14219v1-abstract-full').style.display = 'none'; document.getElementById('2110.14219v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 27 October, 2021; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> October 2021. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">21pages, 20figures</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2110.04750">arXiv:2110.04750</a> <span> [<a href="https://arxiv.org/pdf/2110.04750">pdf</a>, <a href="https://arxiv.org/format/2110.04750">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Plasma Physics">physics.plasm-ph</span> </div> </div> <p class="title is-5 mathjax"> Intermittent excitation of parametric instabilities enhanced by synergistic effect in broadband laser plasma interaction </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Liu%2C+Q">Qingkang Liu</a>, <a href="/search/physics?searchtype=author&query=Zhang%2C+E">Enhao Zhang</a>, <a href="/search/physics?searchtype=author&query=Zhang%2C+W">Wenshuai Zhang</a>, <a href="/search/physics?searchtype=author&query=Cai%2C+H">Hongbo Cai</a>, <a href="/search/physics?searchtype=author&query=Gao%2C+Y">Yanqi Gao</a>, <a href="/search/physics?searchtype=author&query=Zhu%2C+S">Shaoping Zhu</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2110.04750v1-abstract-short" style="display: inline;"> A new evolution pattern for parametric instabilities in the non-linear stage driven by a broadband laser is studied with kinetic particle-in-cell simulations.

It is found that an intermittent excitation of parametric instabilities caused by the high-intensity pulses, which are generated by the laser intensity variation of the broadband laser. The synergism between these high-intensity pulses reduces the Landau damping through the co-propagation of the electron-plasma waves and hot electrons, promoting the transition from convective to absolute stimulated Raman scattering. These intermittently excited parametric instabilities, especially absolute instability, will produce over-expected hot electrons compared with linear theory. However, comparisons between the energy of scattered lights for various bandwidth lasers indicate suppression of parametric instabilities with large laser bandwidths. Our works provided an opportunity to advance the understanding of the broadband laser-plasma interaction. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2110.04750v1-abstract-full').style.display = 'none'; document.getElementById('2110.04750v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 10 October, 2021; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> October 2021. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2107.03669">arXiv:2107.03669</a> <span> [<a href="https://arxiv.org/pdf/2107.03669">pdf</a>, <a href="https://arxiv.org/format/2107.03669">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1007/JHEP11(2021)102">10.1007/JHEP11(2021)102 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Radioactivity control strategy for the JUNO detector </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=JUNO+collaboration"> JUNO collaboration</a>, <a href="/search/physics?searchtype=author&query=Abusleme%2C+A">Angel Abusleme</a>, <a href="/search/physics?searchtype=author&query=Adam%2C+T">Thomas Adam</a>, <a href="/search/physics?searchtype=author&query=Ahmad%2C+S">Shakeel Ahmad</a>, <a href="/search/physics?searchtype=author&query=Ahmed%2C+R">Rizwan Ahmed</a>, <a href="/search/physics?searchtype=author&query=Aiello%2C+S">Sebastiano Aiello</a>, <a href="/search/physics?searchtype=author&query=Akram%2C+M">Muhammad Akram</a>, <a href="/search/physics?searchtype=author&query=An%2C+F">Fengpeng An</a>, <a href="/search/physics?searchtype=author&query=An%2C+Q">Qi An</a>, <a href="/search/physics?searchtype=author&query=Andronico%2C+G">Giuseppe Andronico</a>, <a href="/search/physics?searchtype=author&query=Anfimov%2C+N">Nikolay Anfimov</a>, <a href="/search/physics?searchtype=author&query=Antonelli%2C+V">Vito Antonelli</a>, <a href="/search/physics?searchtype=author&query=Antoshkina%2C+T">Tatiana Antoshkina</a>, <a href="/search/physics?searchtype=author&query=Asavapibhop%2C+B">Burin Asavapibhop</a>, <a href="/search/physics?searchtype=author&query=de+Andr%C3%A9%2C+J+P+A+M">Jo茫o Pedro Athayde Marcondes de Andr茅</a>, <a href="/search/physics?searchtype=author&query=Auguste%2C+D">Didier Auguste</a>, <a href="/search/physics?searchtype=author&query=Babic%2C+A">Andrej Babic</a>, <a href="/search/physics?searchtype=author&query=Baldini%2C+W">Wander Baldini</a>, <a href="/search/physics?searchtype=author&query=Barresi%2C+A">Andrea Barresi</a>, <a href="/search/physics?searchtype=author&query=Basilico%2C+D">Davide Basilico</a>, <a href="/search/physics?searchtype=author&query=Baussan%2C+E">Eric Baussan</a>, <a href="/search/physics?searchtype=author&query=Bellato%2C+M">Marco Bellato</a>, <a href="/search/physics?searchtype=author&query=Bergnoli%2C+A">Antonio Bergnoli</a>, <a href="/search/physics?searchtype=author&query=Birkenfeld%2C+T">Thilo Birkenfeld</a>, <a href="/search/physics?searchtype=author&query=Blin%2C+S">Sylvie Blin</a> , et al.

The expected signal anti-neutrino interaction rate is only 60 counts per day, therefore a careful control of the background sources due to radioactivity is critical. In particular, natural radioactivity present in all materials and in the environment represents a serious issue that could impair the sensitivity of the experiment if appropriate countermeasures were not foreseen. In this paper we discuss the background reduction strategies undertaken by the JUNO collaboration to reduce at minimum the impact of natural radioactivity. We describe our efforts for an optimized experimental design, a careful material screening and accurate detector production handling, and a constant control of the expected results through a meticulous Monte Carlo simulation program. We show that all these actions should allow us to keep the background count rate safely below the target value of 10 Hz in the default fiducial volume, above an energy threshold of 0.7 MeV. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2107.03669v2-abstract-full').style.display = 'none'; document.getElementById('2107.03669v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 13 October, 2021; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 8 July, 2021; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> July 2021. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">35 pages, 12 figures</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2105.03690">arXiv:2105.03690</a> <span> [<a href="https://arxiv.org/pdf/2105.03690">pdf</a>, <a href="https://arxiv.org/format/2105.03690">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Classical Physics">physics.class-ph</span> </div> </div> <p class="title is-5 mathjax"> Elementary Methods for Infinite Resistive Networks with Complex Topologies </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Tran%2C+T+X">Tung X.
