The rapid developing thin-film lithium niobate (TFLN) platform, for its numerous advantages including high electro-optic coefficient and scalability, is well compatible with the realization of synthetic dimensions in the frequency together with spatial domain. While coupling resonators with fixed beam splitters is a common experimental approach, it often lacks tunability and limits coupling between adjacent lattices to sites occupying the same frequency domain positions. Here, on the contrary, we conceive the resonator arrays connected by electro-optic tunable Mach-Zehnder interferometers in our configuration instead of fixed beam splitters. By applying bias voltage and RF modulation on the interferometers, our design extends such coupling to long-range scenario and allows for continuous tuning on each coupling strength and synthetic effective magnetic flux. Therefore, our design enriches controllable coupling types that are essential for building programmable lattice networks and significantly increases versatility. As the example, we experimentally fabricate a two-resonator prototype on the TFLN platform, and on this single chip we realize well-known models including tight-binding lattices, topological Hall ladder and Creutz ladder. We directly observe the band structures in the quasi-momentum space and important phenomena such as spin-momentum locking and the Aharonov-Bohm cage effect. These results demonstrate the potential for convenient simulations of more complex models in our configuration. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2411.13331v1-abstract-full').style.display = 'none'; document.getElementById('2411.13331v1-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 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/2411.10721">arXiv:2411.10721</a> <span> [<a href="https://arxiv.org/pdf/2411.10721">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> </div> </div> <p class="title is-5 mathjax"> High-gain optical parametric amplification with continuous-wave pump using domain-engineered thin film lithium niobate waveguide </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Chen%2C+M">Mengwen Chen</a>, <a href="/search/physics?searchtype=author&query=Wang%2C+C">Chenyu Wang</a>, <a href="/search/physics?searchtype=author&query=Jia%2C+K">Kunpeng Jia</a>, <a href="/search/physics?searchtype=author&query=Tian%2C+X">Xiao-Hui Tian</a>, <a href="/search/physics?searchtype=author&query=Tang%2C+J">Jie Tang</a>, <a href="/search/physics?searchtype=author&query=Zhu%2C+C">Chunxi Zhu</a>, <a href="/search/physics?searchtype=author&query=Gu%2C+X">Xiaowen Gu</a>, <a href="/search/physics?searchtype=author&query=Zhao%2C+Z">Zexing Zhao</a>, <a href="/search/physics?searchtype=author&query=Wang%2C+Z">Zikang Wang</a>, <a href="/search/physics?searchtype=author&query=Ye%2C+Z">Zhilin Ye</a>, <a href="/search/physics?searchtype=author&query=Tang%2C+J">Ji Tang</a>, <a href="/search/physics?searchtype=author&query=Zhang%2C+Y">Yong Zhang</a>, <a href="/search/physics?searchtype=author&query=Yan%2C+Z">Zhong Yan</a>, <a href="/search/physics?searchtype=author&query=Qian%2C+G">Guang Qian</a>, <a href="/search/physics?searchtype=author&query=Jin%2C+B">Biaobing Jin</a>, <a href="/search/physics?searchtype=author&query=Wang%2C+Z">Zhenlin Wang</a>, <a href="/search/physics?searchtype=author&query=Zhu%2C+S">Shi-Ning Zhu</a>, <a href="/search/physics?searchtype=author&query=Xie%2C+Z">Zhenda Xie</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="2411.10721v1-abstract-short" style="display: inline;"> While thin film lithium niobate (TFLN) is known for efficient signal generation, on-chip signal amplification remains challenging from fully integrated optical communication circuits.

However, post-selection effects may also introduce unintended biases in precision measurements. Here, we investigate the influence of post-selection in the precision spectroscopy of the $2^3S - 2^3P$ transition of helium ($^4$He) using an atomic beam. We directly observe that post-selection based on atomic positions causes a shift in the measured transition frequency, amounting to approximately -55 kHz. After accounting for this post-selection shift, we obtain a corrected frequency of $276,764,094,712.45 \pm 0.86$ kHz for the $2^3S_1 - 2^3P_0$ transition. Combining this result with existing data for $^3$He, we derive a new value for the difference in squared nuclear charge radii, $未r^2 [r_{h}^{2} - r_伪^{2}] = 1.0733 \pm 0.0021$ fm$^2$. This value shows a $2.8蟽$ deviation from measurements of muonic helium ions, potentially pointing to new physics that challenges lepton universality in quantum electrodynamics. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2411.09958v1-abstract-full').style.display = 'none'; document.getElementById('2411.09958v1-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 November, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> November 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">14 pages including appendix</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2411.09345">arXiv:2411.09345</a> <span> [<a href="https://arxiv.org/pdf/2411.09345">pdf</a>, <a href="https://arxiv.org/format/2411.09345">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"> DarkSHINE Baseline Design Report: Physics Prospects and Detector Technologies </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Chen%2C+J">Jing Chen</a>, <a href="/search/physics?searchtype=author&query=Chen%2C+J">Ji-Yuan Chen</a>, <a href="/search/physics?searchtype=author&query=Chen%2C+J">Jun-Feng Chen</a>, <a href="/search/physics?searchtype=author&query=Chen%2C+X">Xiang Chen</a>, <a href="/search/physics?searchtype=author&query=Fu%2C+C">Chang-Bo Fu</a>, <a href="/search/physics?searchtype=author&query=Guo%2C+J">Jun Guo</a>, <a href="/search/physics?searchtype=author&query=Guo%2C+Y">Yi-Han Guo</a>, <a href="/search/physics?searchtype=author&query=Khaw%2C+K+S">Kim Siang Khaw</a>, <a href="/search/physics?searchtype=author&query=Li%2C+J">Jia-Lin Li</a>, <a href="/search/physics?searchtype=author&query=Li%2C+L">Liang Li</a>, <a href="/search/physics?searchtype=author&query=Li%2C+S">Shu Li</a>, <a href="/search/physics?searchtype=author&query=Lin%2C+Y">Yu-ming Lin</a>, <a href="/search/physics?searchtype=author&query=Liu%2C+D">Dan-Ning Liu</a>, <a href="/search/physics?searchtype=author&query=Liu%2C+K">Kang Liu</a>, <a href="/search/physics?searchtype=author&query=Liu%2C+K">Kun Liu</a>, <a href="/search/physics?searchtype=author&query=Liu%2C+Q">Qi-Bin Liu</a>, <a href="/search/physics?searchtype=author&query=Liu%2C+Z">Zhi Liu</a>, <a href="/search/physics?searchtype=author&query=Lu%2C+Z">Ze-Jia Lu</a>, <a href="/search/physics?searchtype=author&query=Lv%2C+M">Meng Lv</a>, <a href="/search/physics?searchtype=author&query=Song%2C+S">Si-Yuan Song</a>, <a href="/search/physics?searchtype=author&query=Sun%2C+T">Tong Sun</a>, <a href="/search/physics?searchtype=author&query=Tang%2C+J">Jian-Nan Tang</a>, <a href="/search/physics?searchtype=author&query=Wan%2C+W">Wei-Shi Wan</a>, <a href="/search/physics?searchtype=author&query=Wang%2C+D">Dong Wang</a>, <a href="/search/physics?searchtype=author&query=Wang%2C+X">Xiao-Long Wang</a> , et al.

The precise charge and timing information extracted from the PMT waveform plays a crucial role in energy and vertex reconstruction. In this study, we investigate the deconvolution algorithm utilized for PMT waveform reconstruction, while enhancing the timing separation ability for pile-up hits by redesigning filters based on the time-frequency uncertainty principle. This filter design sacrifices signal-to-noise ratio (SNR) to achieve narrower pulse widths. Furthermore, we optimize the selection of signal pulses in the case of low SNR based on Short-Time Fourier Transform (STFT). Monte Carlo data confirms that our optimization yields enhanced reconstruction performance: improving timing separation ability for pile-up hits from $\sim$10 ns to $3\sim5$ ns, while controlling residual nonlinearity of charge reconstruction within 1\%. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2411.07620v1-abstract-full').style.display = 'none'; document.getElementById('2411.07620v1-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, 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/2411.02966">arXiv:2411.02966</a> <span> [<a href="https://arxiv.org/pdf/2411.02966">pdf</a>, <a href="https://arxiv.org/format/2411.02966">other</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> </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/10.5281/zenodo.13970100">10.5281/zenodo.13970100 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> MuCol Milestone Report No. 5: Preliminary Parameters </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Accettura%2C+C">Carlotta Accettura</a>, <a href="/search/physics?searchtype=author&query=Adrian%2C+S">Simon Adrian</a>, <a href="/search/physics?searchtype=author&query=Agarwal%2C+R">Rohit Agarwal</a>, <a href="/search/physics?searchtype=author&query=Ahdida%2C+C">Claudia Ahdida</a>, <a href="/search/physics?searchtype=author&query=Aim%C3%A9%2C+C">Chiara Aim茅</a>, <a href="/search/physics?searchtype=author&query=Aksoy%2C+A">Avni Aksoy</a>, <a href="/search/physics?searchtype=author&query=Alberghi%2C+G+L">Gian Luigi Alberghi</a>, <a href="/search/physics?searchtype=author&query=Alden%2C+S">Siobhan Alden</a>, <a href="/search/physics?searchtype=author&query=Alfonso%2C+L">Luca Alfonso</a>, <a href="/search/physics?searchtype=author&query=Amapane%2C+N">Nicola Amapane</a>, <a href="/search/physics?searchtype=author&query=Amorim%2C+D">David Amorim</a>, <a href="/search/physics?searchtype=author&query=Andreetto%2C+P">Paolo Andreetto</a>, <a href="/search/physics?searchtype=author&query=Anulli%2C+F">Fabio Anulli</a>, <a href="/search/physics?searchtype=author&query=Appleby%2C+R">Rob Appleby</a>, <a href="/search/physics?searchtype=author&query=Apresyan%2C+A">Artur Apresyan</a>, <a href="/search/physics?searchtype=author&query=Asadi%2C+P">Pouya Asadi</a>, <a href="/search/physics?searchtype=author&query=Mahmoud%2C+M+A">Mohammed Attia Mahmoud</a>, <a href="/search/physics?searchtype=author&query=Auchmann%2C+B">Bernhard Auchmann</a>, <a href="/search/physics?searchtype=author&query=Back%2C+J">John Back</a>, <a href="/search/physics?searchtype=author&query=Badea%2C+A">Anthony Badea</a>, <a href="/search/physics?searchtype=author&query=Bae%2C+K+J">Kyu Jung Bae</a>, <a href="/search/physics?searchtype=author&query=Bahng%2C+E+J">E.

Traditionally, the development of MPPs has relied on a trial-and-error design approach. Although simple optimization-based methods have recently begun to be employed, these designs often overlook practical considerations, such as the increased costs associated with adding more MPP layers, which presents a gap to achieve the practical feasibility of MPP deployment. To address this, the study aims to develop an inverse multi-objective optimization-empowered framework for MPP design to enhance low-frequency noise mitigation while minimizing fabrication costs. Specifically, a finite element (FE) model is established to conduct the acoustic analysis of MPPs, followed by thorough experimental validation. A novel multi-objective particle swarm optimization algorithm (MOPSO) is then developed to cope with mixed-type design variables with interrelations inherent to the MPP architecture. Using the high-fidelity FE model as a cornerstone, the MOPSO guides the inverse optimization analysis to yield multiple non-dominant solutions. These solutions not only avoid the trap of local optima, but also allow for continuous screening to ensure the engineering viability based on empirical judgment. The results clearly demonstrate the effectiveness of the proposed methodology. The MPPs designed in this study show great potential for mitigating indoor noise in buildings, addressing noise issues arising from rapid urbanization and transportation development. Furthermore, the novel optimization strategy proposed in this study holds wide applicability for other sound absorption materials. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2410.05635v1-abstract-full').style.display = 'none'; document.getElementById('2410.05635v1-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 October, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> October 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">32 pages, 11 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/2410.05155">arXiv:2410.05155</a> <span> [<a href="https://arxiv.org/pdf/2410.05155">pdf</a>, <a href="https://arxiv.org/format/2410.05155">other</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"> Formation of Anisotropic Polarons in Antimony Selenide </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Shi%2C+Y">Yijie Shi</a>, <a href="/search/physics?searchtype=author&query=Wang%2C+X">Xi Wang</a>, <a href="/search/physics?searchtype=author&query=Wang%2C+Z">Zhong Wang</a>, <a href="/search/physics?searchtype=author&query=Zhang%2C+Z">Zheng Zhang</a>, <a href="/search/physics?searchtype=author&query=Hua%2C+F">Fuyong Hua</a>, <a href="/search/physics?searchtype=author&query=Chen%2C+C">Chao Chen</a>, <a href="/search/physics?searchtype=author&query=Hu%2C+C">Chunlong Hu</a>, <a href="/search/physics?searchtype=author&query=Tang%2C+J">Jiang Tang</a>, <a href="/search/physics?searchtype=author&query=Liang%2C+W">Wenxi Liang</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="2410.05155v1-abstract-short" style="display: inline;"> Antimony Selenide (Sb$_2$Se$_3$) is an attractive candidate of photovoltaics with not yet satisfying efficiency.

Beside defects, polaron formation originated from lattice distortion was proposed to account for trapping free carriers, and the subsequent photoexcitation dynamics and optoelectronic properties, but such a mechanism is still lack of structural observations. Here we directly track the pathways of carrier and lattice evolutions after photoexcitation through optical and electron diffraction pump-probe methods, revealing the temporal correlations between dynamics of both degrees of freedom. The observed opposite separation changes of Se2-Sb2 and Sb2-Sb1 atom pairs in a few picoseconds, and the intermediate state induced by local structural distortions lasting several tens of picoseconds, coinciding with the optical phonons population and coupling, and the trapping process of carriers, respectively, together with the analyses of modulation on diffuse scattering by the atomic displacement fields of polaron model, indicate the formation of anisotropic polarons with large size. Our findings provide carrier and structural information for helping the elucidation of polaron scenario in Sb2Se3, and probably in materials with anisotropic structure and soft lattice which are popular in developing novel optoelectronics. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2410.05155v1-abstract-full').style.display = 'none'; document.getElementById('2410.05155v1-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 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/2408.17114">arXiv:2408.17114</a> <span> [<a href="https://arxiv.org/pdf/2408.17114">pdf</a>, <a href="https://arxiv.org/format/2408.17114">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"> Design of a CsI(Tl) Calorimeter for Muonium-to-Antimuonium Conversion Experiment </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Chen%2C+S">Siyuan Chen</a>, <a href="/search/physics?searchtype=author&query=Zhao%2C+S">Shihan Zhao</a>, <a href="/search/physics?searchtype=author&query=Xiong%2C+W">Weizhi Xiong</a>, <a href="/search/physics?searchtype=author&query=Tian%2C+Y">Ye Tian</a>, <a href="/search/physics?searchtype=author&query=Jiang%2C+H">Hui Jiang</a>, <a href="/search/physics?searchtype=author&query=Ling%2C+J">Jiacheng Ling</a>, <a href="/search/physics?searchtype=author&query=Wang%2C+S">Shishe Wang</a>, <a href="/search/physics?searchtype=author&query=Tang%2C+J">Jian Tang</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="2408.17114v2-abstract-short" style="display: inline;"> The Muonium-to-Antimuonium Conversion Experiment (MACE) is proposed to search for charged lepton flavor violation and increase the sensitivity by three orders of magnitude compared to the PSI experiment in the 1990s.

It determines the presence of boundary states, while lacking direct measurements. Here, we develop time-varying programmable coupling circuits between acoustic cavities to mimic the Hamiltonians in the Brillouin zone, with which excitation and adiabatic evolution of bulk states are realized in a unit cell. By extracting the Berry phases of the bulk band, topological invariants, including the Zak phase for the SSH model and the Chern number for the AAH model, are obtained convincingly. The bulk state evolution also provides insight into the topological charges of our newly developed non-Abelian models, which are also verified by observing the adiabatic eigenframe rotation.

Its electromagnetic calorimeter is primarily responsible for accurately reconstructing the energy of the recoil electrons and bremsstrahlung photons. The performance of the electromagnetic calorimeter is crucial, as its energy measurement precision directly determines the sensitivity to the search for dark photons. The DarkSHINE electromagnetic calorimeter uses LYSO crystals to form a fully absorptive electromagnetic calorimeter. It utilizes SiPMs to detect scintillation light in the crystals, and its readout electronics system deduces the deposited energy in the crystals by measuring the number of photoelectric signals generated by the SiPMs. The DarkSHINE electromagnetic calorimeter aims to operate at an event rate of 1-10 MHz, detecting energies ranging from 1 MeV to 1 GeV. To meet the requirements of high energy measurement precision, high event rate, and large dynamic range, we have researched and designed a readout electronics system based on dual-channel high-speed ADCs and a customized DAQ. The front-end amplification part of this system uses low-noise trans-impedance amplifiers to achieve high-precision waveform amplification. It successfully achieves a dynamic range up to a thousandfold through a double-gain readout scheme. The digital part uses 1 GSPS high-speed ADCs to achieve non-dead-time, high-precision waveform digitization. The DAQ part uses JESD204B high-speed serial protocol to read out the signal from ADC, and transmit it to PC software for processing and storage. Test results show a signal-to-noise ratio greater than 66 dBFS and an ENOB greater than 10.6 bits. Energy spectra measurements have been conducted using LYSO crystals and SiPMs, and an energy resolution of 5.96% at the 2.6 MeV gamma peak of Th-232 has been achieved. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2407.20723v1-abstract-full').style.display = 'none'; document.getElementById('2407.20723v1-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> 30 July, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> July 2024. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2407.17800">arXiv:2407.17800</a> <span> [<a href="https://arxiv.org/pdf/2407.17800">pdf</a>, <a href="https://arxiv.org/format/2407.17800">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"> Design of a LYSO Crystal Electromagnetic Calorimeter for DarkSHINE Experiment </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Zhao%2C+Z">Zhiyu Zhao</a>, <a href="/search/physics?searchtype=author&query=Liu%2C+Q">Qibin Liu</a>, <a href="/search/physics?searchtype=author&query=Chen%2C+J">Jiyuan Chen</a>, <a href="/search/physics?searchtype=author&query=Chen%2C+J">Jing Chen</a>, <a href="/search/physics?searchtype=author&query=Chen%2C+J">Junfeng Chen</a>, <a href="/search/physics?searchtype=author&query=Chen%2C+X">Xiang Chen</a>, <a href="/search/physics?searchtype=author&query=Fu%2C+C">Changbo Fu</a>, <a href="/search/physics?searchtype=author&query=Guo%2C+J">Jun Guo</a>, <a href="/search/physics?searchtype=author&query=Khaw%2C+K+S">Kim Siang Khaw</a>, <a href="/search/physics?searchtype=author&query=Li%2C+L">Liang Li</a>, <a href="/search/physics?searchtype=author&query=Li%2C+S">Shu Li</a>, <a href="/search/physics?searchtype=author&query=Liu%2C+D">Danning Liu</a>, <a href="/search/physics?searchtype=author&query=Liu%2C+K">Kun Liu</a>, <a href="/search/physics?searchtype=author&query=Song%2C+S">Siyuan Song</a>, <a href="/search/physics?searchtype=author&query=Sun%2C+T">Tong Sun</a>, <a href="/search/physics?searchtype=author&query=Tang%2C+J">Jiannan Tang</a>, <a href="/search/physics?searchtype=author&query=Wang%2C+Y">Yufeng Wang</a>, <a href="/search/physics?searchtype=author&query=Wang%2C+Z">Zhen Wang</a>, <a href="/search/physics?searchtype=author&query=Wu%2C+W">Weihao Wu</a>, <a href="/search/physics?searchtype=author&query=Yang%2C+H">Haijun Yang</a>, <a href="/search/physics?searchtype=author&query=Lin%2C+Y">Yuming Lin</a>, <a href="/search/physics?searchtype=author&query=Yuan%2C+R">Rui Yuan</a>, <a href="/search/physics?searchtype=author&query=Zhang%2C+Y">Yulei Zhang</a>, <a href="/search/physics?searchtype=author&query=Zhang%2C+Y">Yunlong Zhang</a>, <a href="/search/physics?searchtype=author&query=Zhou%2C+B">Baihong Zhou</a> , et al.

The ECAL configuration consists of 21$\times$21$\times$11 LYSO crystals, each measuring 2.5$\times$2.5$\times$4 cm$^3$, arranged in a staggered layout to improve signal detection efficiency. A 4 GeV energy dynamic range was established to ensure accurate energy measurements without saturation, which is essential for background rejection and signal identification. A detailed digitization model was developed to simulate the scintillation, SiPM, and ADC behaviors, providing a more realistic representation of detector performance. Additionally, the study assessed radiation damage in the ECAL region, highlighting the necessity of radiation-resistant scintillators and silicon sensors. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2407.17800v2-abstract-full').style.display = 'none'; document.getElementById('2407.17800v2-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 October, 2024; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 25 July, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> July 2024. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2407.14553">arXiv:2407.14553</a> <span> [<a href="https://arxiv.org/pdf/2407.14553">pdf</a>, <a href="https://arxiv.org/format/2407.14553">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="Applied Physics">physics.app-ph</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"> Machine Learning for Improved Current Density Reconstruction from 2D Vector Magnetic Images </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Reed%2C+N+R">Niko R.

Analytic reconstruction methods exist for planar currents, but break down in the presence of high spatial frequency noise or large standoff distance, restricting the types of systems that can be studied. Here, we demonstrate the use of a deep convolutional neural network for current density reconstruction from two-dimensional (2D) images of vector magnetic fields acquired by a quantum diamond microscope (QDM) utilizing a surface layer of Nitrogen Vacancy (NV) centers in diamond. Trained network performance significantly exceeds analytic reconstruction for data with high noise or large standoff distances. This machine learning technique can perform quality inversions on lower SNR data, reducing the data collection time by a factor of about 400 and permitting reconstructions of weaker and three-dimensional current sources. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2407.14553v2-abstract-full').style.display = 'none'; document.getElementById('2407.14553v2-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> 3 August, 2024; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 18 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">17 pages, 10 figures.

Conventional methods alter the eigenmode of the optical cavity by regulating the refractive index. Due to the weak nonlinear effect of the optical system, the device must be sufficiently large to achieve sufficient light modulation. The effective method for miniaturizing beam steering devices currently in use is based on metasurfaces. However, this type of device necessitates the input of a laser source, which precludes the simultaneous generation and control of light in a single device. Here we propose a miniaturized beam steering device that employs mode selection between different bound states in the continuum (BIC) states through phase change material. The device is capable of simultaneously achieving both light generation and beam steering (33掳) in a single device with a size of only 25 渭m and with a low threshold of 8.9 kW cm-2. Furthermore,it is possible to achieve a significant degree of dynamic wavelength tunability, with a range extending up to 296 nm. This method achieves high-efficient regulation of light properties by dynamically controlling the system's topological charge, circumventing the problem of weak nonlinearity in traditional methods. Furthermore, the integration of phase change materials with nanolasers enables the direct alteration of lasing properties, which provides a novel idea for dynamic light control. The device process scheme based on phase change materials is straightforward, direct, and highly compatible, which will be advantageous for its intended application. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2407.14036v1-abstract-full').style.display = 'none'; document.getElementById('2407.14036v1-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 July, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> July 2024. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2407.12450">arXiv:2407.12450</a> <span> [<a href="https://arxiv.org/pdf/2407.12450">pdf</a>, <a href="https://arxiv.org/format/2407.12450">other</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="High Energy Physics - Experiment">hep-ex</span> </div> </div> <p class="title is-5 mathjax"> Interim report for the International Muon Collider Collaboration (IMCC) </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Accettura%2C+C">C.

The Muon Collider Study (MuC) covers the accelerator complex, detectors and physics for a future muon collider. In 2023, European Commission support was obtained for a design study of a muon collider (MuCol) [3]. This project started on 1st March 2023, with work-packages aligned with the overall muon collider studies. In preparation of and during the 2021-22 U.S. Snowmass process, the muon collider project parameters, technical studies and physics performance studies were performed and presented in great detail. Recently, the P5 panel [4] in the U.S. recommended a muon collider R&D, proposed to join the IMCC and envisages that the U.S. should prepare to host a muon collider, calling this their "muon shot". In the past, the U.S. Muon Accelerator Programme (MAP) [5] has been instrumental in studies of concepts and technologies for a muon collider. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2407.12450v1-abstract-full').style.display = 'none'; document.getElementById('2407.12450v1-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 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">This document summarises the International Muon Collider Collaboration (IMCC) progress and status of the Muon Collider R&D programme</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.

The absolute branching fractions of $D_{s1}(2536)^- \rightarrow \bar{D}^{*0}K^-$ and $D_{s2}^*(2573)^- \rightarrow \bar{D}^0K^-$ are measured for the first time to be $(35.9\pm 4.8\pm 3.5)\%$ and $(37.4\pm 3.1\pm 4.6)\%$, respectively. The measurements are in tension with predictions based on the assumption that the $D_{s1}(2536)$ and $D_{s2}^*(2573)$ are dominated by a bare $c\bar{s}$ component. The $e^+e^-\rightarrow D_s^+D_{s1}(2536)^-$ and $e^+e^-\rightarrow D_s^+D^*_{s2}(2573)^-$ cross sections are measured, and a resonant structure at around 4.6~GeV with a width of 50~MeV is observed for the first time with a statistical significance of $15蟽$ in the $e^+e^-\rightarrow D_s^+D^*_{s2}(2573)^-$ process. It could be the $Y(4626)$ found by the Belle collaboration in the $D_s^+D_{s1}(2536)^{-}$ final state, since they have similar masses and widths.

In the present work, we integrate a QDM with a narrowband measurement protocol and a lock-in camera; and demonstrate imaging of radiofrequency (RF) magnetic field patterns produced by microcoils, with spectral resolution $\approx1$\,Hz. This RF-QDM provides multi-frequency imaging with a central detection frequency that is easily tunable over the MHz-scale, allowing spatial discrimination of both crowded spectral peaks and spectrally well-separated signals. The present instrument has spatial resolution $\approx2\,\mathrm{渭m}$, field-of-view $\approx300\times300\,\mathrm{渭m^2}$, and per-pixel sensitivity to narrowband fields $\sim{1}\,$nT$\cdot$Hz$^{-1/2}$. Spatial noise can be reduced to the picotesla scale by signal averaging and/or spatial binning. The RF-QDM enables simultaneous imaging of the amplitude, frequency, and phase of narrowband magnetic field patterns at the micron-scale, with potential applications in real-space NMR imaging, AC susceptibility mapping, impedance tomography, analysis of electronic circuits, and spatial eddy-current-based inspection. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2406.15450v2-abstract-full').style.display = 'none'; document.getElementById('2406.15450v2-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 October, 2024; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 6 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/2406.12522">arXiv:2406.12522</a> <span> [<a href="https://arxiv.org/pdf/2406.12522">pdf</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="Atmospheric and Oceanic Physics">physics.ao-ph</span> </div> </div> <p class="title is-5 mathjax"> Photohermal Microswimmer Penetrate Cell Membrane with Cavitation Bubble </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Zeng%2C+B">Binglin Zeng</a>, <a href="/search/physics?searchtype=author&query=Lai%2C+J">Jialin Lai</a>, <a href="/search/physics?searchtype=author&query=Chen%2C+J">Jingyuan Chen</a>, <a href="/search/physics?searchtype=author&query=Huang%2C+Y">Yaxin Huang</a>, <a href="/search/physics?searchtype=author&query=Wu%2C+C">Changjin Wu</a>, <a href="/search/physics?searchtype=author&query=Huang%2C+C">Chao Huang</a>, <a href="/search/physics?searchtype=author&query=Guo%2C+Q">Qingxin Guo</a>, <a href="/search/physics?searchtype=author&query=Li%2C+X">Xiaofeng Li</a>, <a href="/search/physics?searchtype=author&query=Li%2C+S">Shuai Li</a>, <a href="/search/physics?searchtype=author&query=Tang%2C+J">Jinyao Tang</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="2406.12522v2-abstract-short" style="display: inline;"> Self-propelled micromotors can efficiently convert ambient energy into mechanical motion, which is of great interest for its potential biomedical applications in delivering therapeutics noninvasively.

However, navigating these micromotors through biological barriers remains a significant challenge as most micromotors do not provide sufficient disruption forces in in-vivo conditions. In this study, we employed focused scanning laser from conventional confocal microscope to manipulate carbon microbottle based microswimmers. With the increasing of the laser power, the microswimmers' motions translates from autonomous to directional, and finally the high power laser induced the microswimmer explosions, which effectively deliveres microbottle fragments through the cell membrane. It is revealed that photothermally-induced cavitation bubbles enable the propulsion of microbottles in liquids, where the motion direction can be precisely regulated by the scanning orientation of the laser. Furthermore, the membrane penetration ability of the microbottles promised potential applications in drug delivery and cellular injections. As microbottles navigate toward cells, we strategically increase the laser power to trigger their explosion. By loading microswimmers with transfection genes, cytoplasmic transfection can be realized, which is demonstrated by successful gene transfection of GPF in cells. Our findings open new possibilities for cell injection and gene transfection using micromotors. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2406.12522v2-abstract-full').style.display = 'none'; document.getElementById('2406.12522v2-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, 2024; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 18 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">30 pages, 6 figures</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">MSC Class:</span> 00Axx </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2406.01944">arXiv:2406.01944</a> <span> [<a href="https://arxiv.org/pdf/2406.01944">pdf</a>, <a href="https://arxiv.org/format/2406.01944">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"> A table-top high-sensitivity gyroscope based on slow light and cavity enhanced photon drag </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=She%2C+M">Min She</a>, <a href="/search/physics?searchtype=author&query=Tang%2C+J">Jiangshan Tang</a>, <a href="/search/physics?searchtype=author&query=Xia%2C+K">Keyu Xia</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="2406.01944v1-abstract-short" style="display: inline;"> A high-sensitivity gyroscope is vital for both investigation of the fundamental physics and monitor of the subtle variation of Earth's behaviors.

However, it is challenge to realize a portable gyroscope with sensitivity approaching a small fraction of the Earth's rotation rate. Here, we theoretically propose a method for implementing a table-top gyroscope with remarkably high sensitivity based on photon drag in a rotating dielectric object. By inserting an $\text{Er}^{3+}$-doped glass rod in a Fabry-P茅rot optical cavity with only 20 cm length, we theoretically show that the giant group refractive index and the narrowing cavity linewidth due to slow light can essentially increase the nonreciprocal phase shift due to the photon drag to achieve a rotation sensitivity of $26$ frad/s/$\sqrt{Hz}$. This work paves the way to accurately detect tiny variations of the Earth's rotation rate and orientation, and even can test the geodetic and frame-dragging effects predicted by the general relativity with a small-volume equipment. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2406.01944v1-abstract-full').style.display = 'none'; document.getElementById('2406.01944v1-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> 3 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/2405.07303">arXiv:2405.07303</a> <span> [<a href="https://arxiv.org/pdf/2405.07303">pdf</a>, <a href="https://arxiv.org/format/2405.07303">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> <p class="title is-5 mathjax"> Search for solar axions by Primakoff effect with the full dataset of the CDEX-1B Experiment </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Yang%2C+L+T">L.

A three-body system of electrons (e) and holes (h) (2e1h, or 1e2h) in a two-band semiconductor is commonly believed to be associated with two spectral peaks for the exciton and trion (or charged exciton), respectively. But both the validity of this understanding and the physical meaning of a trion or charged exciton have not been thoroughly examined. From the physics point of view, there are two different configurations, (e)(eh) or (eeh), which could be considered charged exciton and trion, respectively. Here (...) represents an irreducible cluster with respect to Coulomb interactions. In this paper, we consider these issues related to the 2e1h three-body problem theoretically and experimentally using monolayer MoTe2 as an example. Our theoretical tools involve the three-body Bethe-Salpeter Equation (BSE) and the cluster expansion technique, especially their correspondence. Experimentally, we measure the photoluminescence spectrum on a gate-controlled monolayer MoTe2. We found two spectral peaks that are 21 and 4 meV, respectively, below the exciton peak, in contrast to the single "trion" peak from the conventional understanding. We show that, while the three-body BSE in a two-band model can reproduce all spectral features, the cluster-expansion technique shows that the two peaks correspond to the charged exciton (e)(eh) and trion (eeh), respectively. In other words, there is a spectral splitting due to the two different many-body configurations. Furthermore, we find that the trion only exists in the intervalley case, while the charged exciton exists both for the intervalley and intravalley cases. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2405.01862v1-abstract-full').style.display = 'none'; document.getElementById('2405.01862v1-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> 3 May, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> May 2024. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2405.01853">arXiv:2405.01853</a> <span> [<a href="https://arxiv.org/pdf/2405.01853">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="Computational Physics">physics.comp-ph</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"> Spectral Features of the Fourth Order Irreducible Correlations in a Monolayer Semiconductor </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Tang%2C+J">Jiacheng Tang</a>, <a href="/search/physics?searchtype=author&query=Ning%2C+C">Cun-Zheng Ning</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="2405.01853v1-abstract-short" style="display: inline;"> Understanding high-order correlations or multi-particle entities in a many-body system is not only of fundamental importance in condensed matter physics, but also critical for many technological applications.

So far, higher-order multi-particle irreducible correlations in semiconductors have not been studied beyond the second-order or two-particle case. In this paper, we study the correlation of two electrons and two holes (2e2h) using the four-body Bethe-Salpeter equation (4B-BSE) and applied to the calculation of the helicity-resolved absorption between the two-body and four-body states for a monolayer MoTe2. Surprisingly, we found a rich series of spectral peaks within an energy span of ~40 meV below the exciton that has not been seen before. To understand the origin of the new spectral peaks, the Feynman diagrams of the 4B BSE are recast into the cluster expansion formalism, allowing us to study the individual effects of selected clusters or correlations of various orders. We found that the irreducible clusters of orders up to the 3rd and their factorized combinations cannot explain the spectral features. Importantly, we found that the 4th order irreducible correlation is necessary and sufficient to explain the new features. The 4th order irreducible correlation corresponds to a four-particle irreducible cluster involving two electrons and two holes, alternatively called quadron or quadruplon. The new 4th order correlation or four-particle entity not only enriches our understanding of many-body correlations but also could provide new mechanism for light emission or absorption for possible new optoelectronic devices. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2405.01853v1-abstract-full').style.display = 'none'; document.getElementById('2405.01853v1-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> 3 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">Comments:</span> <span class="has-text-grey-dark mathjax">arXiv admin note: text overlap with arXiv:2207.12760</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2405.01626">arXiv:2405.01626</a> <span> [<a href="https://arxiv.org/pdf/2405.01626">pdf</a>, <a href="https://arxiv.org/format/2405.01626">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Cosmology and Nongalactic Astrophysics">astro-ph.CO</span> <span class="tag is-small is-grey 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="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> <p class="title is-5 mathjax"> Mineral Detection of Neutrinos and Dark Matter 2024.

This document collects contributions from this workshop, providing an overview of activities in the field. MDvDM'24 was the second topical workshop dedicated to the emerging field of mineral detection of neutrinos and dark matter, following a meeting hosted by IFPU in Trieste, Italy in October 2022. Mineral detectors have been proposed for a wide variety of applications, including searching for dark matter, measuring various fluxes of astrophysical neutrinos over gigayear timescales, monitoring nuclear reactors, and nuclear disarmament protocols; both as paleo-detectors using natural minerals that could have recorded the traces of nuclear recoils for timescales as long as a billion years and as detectors recording nuclear recoil events on laboratory timescales using natural or artificial minerals. Contributions to this proceedings discuss the vast physics potential, the progress in experimental studies, and the numerous challenges lying ahead on the path towards mineral detection. These include a better understanding of the formation and annealing of recoil defects in crystals; identifying the best classes of minerals and, for paleo-detectors, understanding their geology; modeling and control of the relevant backgrounds; developing, combining, and scaling up imaging and data analysis techniques; and many others. During the last years, MDvDM has grown rapidly and gained attention. Small-scale experimental efforts focused on establishing various microscopic readout techniques are underway at institutions in North America, Europe and Asia. We are looking ahead to an exciting future full of challenges to overcome, surprises to be encountered, and discoveries lying ahead of us. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2405.01626v1-abstract-full').style.display = 'none'; document.getElementById('2405.01626v1-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 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">Comments:</span> <span class="has-text-grey-dark mathjax">Summary and proceedings of the MDvDM'24 conference, Jan 8-11 2024</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2405.00299">arXiv:2405.00299</a> <span> [<a href="https://arxiv.org/pdf/2405.00299">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="Applied Physics">physics.app-ph</span> </div> </div> <p class="title is-5 mathjax"> Thermal stability and phase transformation of $伪$-, $魏(蔚)$-, and $纬$-Ga$_2$O$_3$ thin films to $尾$-Ga$_2$O$_3$ under various ambient conditions </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Tang%2C+J">J.

Particular crystallographic orientation relationships were observed before and after the phase transitions, i.e., (0006) $伪$-Ga$_2$O$_3$ $\parallel$ $(\overline{4}02)$ $尾$-Ga$_2$O$_3$, (004) $魏(蔚)$-Ga$_2$O$_3$ $\parallel$ (310) and $(\overline{4}02)$ $尾$-Ga$_2$O$_3$, and (400) $纬$-Ga$_2$O$_3$ $\parallel$ (400) $尾$-Ga$_2$O$_3$. The phase transition of $伪$-Ga$_2$O$_3$ to $尾$-Ga$_2$O$_3$ resulted in catastrophic damage to the film and upheaval of the surface. The respective primary and possibly secondary causes of this damage are the +8.6% volume expansion and the dual displacive and reconstructive transformations that occur during this transition. The $魏(蔚)$- and $纬$-Ga$_2$O$_3$ films converted to $尾$-Ga$_2$O$_3$ via singular reconstructive transformations with small changes in volume and unchanged surface microstructures. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2405.00299v1-abstract-full').style.display = 'none'; document.getElementById('2405.00299v1-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> 30 April, 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">Comments:</span> <span class="has-text-grey-dark mathjax">15 pages, 6 figures, 1 table</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2404.14673">arXiv:2404.14673</a> <span> [<a href="https://arxiv.org/pdf/2404.14673">pdf</a>, <a href="https://arxiv.org/format/2404.14673">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="Optics">physics.optics</span> </div> </div> <p class="title is-5 mathjax"> High-Dimensional Two-Photon Quantum Controlled Phase-Flip Gate </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Chen%2C+M">Mingyuan Chen</a>, <a href="/search/physics?searchtype=author&query=Tang%2C+J">Jiangshan Tang</a>, <a href="/search/physics?searchtype=author&query=Cai%2C+M">Miao Cai</a>, <a href="/search/physics?searchtype=author&query=Nori%2C+F">Franco Nori</a>, <a href="/search/physics?searchtype=author&query=Xia%2C+K">Keyu Xia</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="2404.14673v1-abstract-short" style="display: inline;"> High-dimensional quantum systems have been used to reveal interesting fundamental physics and to improve information capacity and noise resilience in quantum information processing.

However, it remains a significant challenge to realize universal two-photon quantum gates in high dimensions with high success probability. Here, by considering an ion-cavity QED system, we theoretically propose, to the best of our knowledge, the first high-dimensional, deterministic and universal two-photon quantum gate. By using an optical cavity embedded with a single trapped 40Ca+ ion, we achieve a high average fidelity larger than 98% for a quantum controlled phase-flip gate in four-dimensional space, spanned by photonic spin angular momenta and orbital angular momenta. Our proposed system can be an essential building block for high-dimensional quantum information processing, and also provides a platform for studying high-dimensional cavity QED. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2404.14673v1-abstract-full').style.display = 'none'; document.getElementById('2404.14673v1-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> 22 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/2404.10470">arXiv:2404.10470</a> <span> [<a href="https://arxiv.org/pdf/2404.10470">pdf</a>, <a href="https://arxiv.org/ps/2404.10470">ps</a>, <a href="https://arxiv.org/format/2404.10470">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> </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/10.1088/0256-307X/41/4/044205">10.1088/0256-307X/41/4/044205 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Reversible optical isolators and quasi-circulators using a magneto-optical Fabry-P茅rot cavity </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Zhang%2C+T">Tiantian Zhang</a>, <a href="/search/physics?searchtype=author&query=Zhou%2C+W">Wenpeng Zhou</a>, <a href="/search/physics?searchtype=author&query=Li%2C+Z">Zhixiang Li</a>, <a href="/search/physics?searchtype=author&query=Tang%2C+Y">Yutao Tang</a>, <a href="/search/physics?searchtype=author&query=Xu%2C+F">Fan Xu</a>, <a href="/search/physics?searchtype=author&query=Wu%2C+H">Haodong Wu</a>, <a href="/search/physics?searchtype=author&query=Zhang%2C+H">Han Zhang</a>, <a href="/search/physics?searchtype=author&query=Tang%2C+J">Jiang-Shan Tang</a>, <a href="/search/physics?searchtype=author&query=Ruan%2C+Y">Ya-Ping Ruan</a>, <a href="/search/physics?searchtype=author&query=Xia%2C+K">Keyu Xia</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="2404.10470v1-abstract-short" style="display: inline;"> Nonreciprocal optical devices are essential for laser protection, modern optical communication and quantum information processing by enforcing one-way light propagation.

The conventional Faraday magneto-optical nonreciprocal devices rely on a strong magnetic field, which is provided by a permanent magnet. As a result, the isolation direction of such devices is fixed and severely restricts their applications in quantum networks.In this work, we experimentally demonstrate the simultaneous one-way transmission and unidirectional reflection by using a magneto-optical Fabry-P茅rot cavity and a magnetic field strength of $50~\milli\tesla$. An optical isolator and a three-port quasi-circulator are realized based on this nonreciprocal cavity system. The isolator achieves an isolation ratio of up to $22~\deci\bel$ and an averaged insertion loss down to $0.97~\deci\bel$. The quasi-circulator is realized with a fidelity exceeding $99\%$ and an overall survival probability of $89.9\%$, corresponding to an insertion loss of $\sim 0.46~\deci\bel$. The magnetic field is provided by an electromagnetic coil, thereby allowing for reversing the light circulating path. The reversible quasi-circulator paves the way for building reconfigurable quantum networks. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2404.10470v1-abstract-full').style.display = 'none'; document.getElementById('2404.10470v1-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 April, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> April 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">8 pages, 7 figures</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Chinese Physics Letters 4 (2024), 044205 </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2404.09793">arXiv:2404.09793</a> <span> [<a href="https://arxiv.org/pdf/2404.09793">pdf</a>, <a href="https://arxiv.org/format/2404.09793">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> <p class="title is-5 mathjax"> First Search for Light Fermionic Dark Matter Absorption on Electrons Using Germanium Detector in CDEX-10 Experiment </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Liu%2C+J+X">J.

There is a novel concept of detecting $蠂$ from evaporating primordial black holes (PBHs). We search for $蠂$ emitted from PBHs by investigating their interaction with target electrons. The examined PBH masses range from 1$\times$10$^{15}$ to 7$\times$10$^{16}$ g under the current limits of PBH abundance $f_{PBH}$. Using 205.4 kg$\cdot$day data obtained from the CDEX-10 experiment conducted in the China Jinping Underground Laboratory, we exclude the $蠂$--electron ($蠂$--$e$) elastic-scattering cross section $蟽_{蠂e} \sim 5\times10^{-29}$ cm$^2$ for $蠂$ with a mass $m_蠂\lesssim$ 0.1 keV from our results. With the higher radiation background but lower energy threshold (160 eV), CDEX-10 fill a part of the gap in the previous work. If ($m_蠂$, $蟽_{蠂e}$) can be determined in the future, DD experiments are expected to impose strong constraints on $f_{PBH}$ for large $M_{PBH}$s. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2403.20263v2-abstract-full').style.display = 'none'; document.getElementById('2403.20263v2-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> 22 September, 2024; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 29 March, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> March 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">9 pages, 6 figures, 3 tables.

However, the time resolution significantly degrades for large-area SiPMs due to the large detector capacitance, posing significant challenges for the readout electronics of SiPMs in hDOM. We analyzed the influences of series and parallel connections when constructing a large-area SiPM array and designed a series-parallel connection SiPM array with differential output. We also designed a high-speed pre-amplifier based on transformers (MABA-007159) and radio frequency amplifiers (BGA2803), and an analog multi-channel summing circuit based on operational amplifiers (LMH6629). We measured the single photon time resolution (SPTR) of a $4\times4$ SiPM (Hamamatsu S13360-3050PE) array ($12\times12~\mathrm{mm}^2$) of approximately 300 ps FWHM. This front-end readout design enables the large-area SiPM array to achieve high-precision single photon time measurement in one readout channel. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2403.02948v2-abstract-full').style.display = 'none'; document.getElementById('2403.02948v2-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 June, 2024; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 5 March, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> March 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">Revised version. 12 pages, 10 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/2403.00308">arXiv:2403.00308</a> <span> [<a href="https://arxiv.org/pdf/2403.00308">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> </div> </div> <p class="title is-5 mathjax"> Longitudinal beam dynamics design fpr Super Tau-Charm Facility </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Zhang%2C+L">Linhao Zhang</a>, <a href="/search/physics?searchtype=author&query=Liu%2C+T">Tao Liu</a>, <a href="/search/physics?searchtype=author&query=Li%2C+S">Sangya Li</a>, <a href="/search/physics?searchtype=author&query=Tang%2C+J">Jingyu Tang</a>, <a href="/search/physics?searchtype=author&query=Luo%2C+Q">Qing Luo</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="2403.00308v1-abstract-short" style="display: inline;"> The project of Super Tau-Charm Facility (STCF) proposed in China, as a new-generation high-luminosity $e^+e^-$ collider in the low-energy region with the center-of-mass energy of 2-7 GeV, is well underway.

The luminosity is targeted at $1.0\times10^{35} cm^{-2}s^{-1}$ at the optimized beam energy of 2 GeV. Longitudinal beam dynamics becomes of great importance for the STCF due to the constraints from the novel beam-beam effect called coherent X-Z instability and severe beam collective effects.

However, current THz detection devices have limitations in sensitivity, operating frequency range, and bulky footprint. While recent ferroelectric-integrated graphene plasmonic devices show promise in overcoming these limitations, they are not yet extended to the THz range. Here, we propose a wavelength-sensitive terahertz detector that uses a single layer graphene integrated onto the ferroelectric thin film with patterned polarization domains. This device works at room temperature, with high responsivity and detectivity by coupling graphene plasmons with THz frequencies through spatial modulation of carrier behaviors using ferroelectric polarization, without requiring additional local electrodes. By reconfiguring an interweaving squared ferroelectric domain array with alternating upward and downward polarizations to highly confine graphene surface plasmon polaritons, our device achieves an ultrahigh responsivity of 1717 A W-1 and a normalized detectivity of 1.07*10^13 Jones at a resonance frequency of 6.30 THz and a 0.3 V bias voltage.

A multi-cubic-kilometer neutrino telescope, TRopIcal DEep-sea Neutrino Telescope (TRIDENT), was proposed to be built in the South China Sea. The detector aims to achieve ~ 0.1 degree angular resolution for track-like events at energy above 100 TeV by using hybrid digital optical modules, opening new opportunities for neutrino astronomy. In order to measure the water optical properties and marine environment of the proposed TRIDENT site, a pathfinder experiment was conducted, in which a 100-meter-long string consisting of three optical modules was deployed at a depth of 3420 m to perform in-situ measurements. The central module emits light by housing LEDs, whereas the other two modules detect light with two independent and complementary systems: the PMT and the camera systems. By counting the number of detected photons and analyzing the photon arrival time distribution, the PMT system can measure the absorption and scattering lengths of sea water, which serve as the basic inputs for designing the neutrino telescope. In this paper, we present the design concept, calibration and performance of the PMT system in the pathfinder experiment. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2312.12327v1-abstract-full').style.display = 'none'; document.getElementById('2312.12327v1-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 December, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> December 2023. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2312.11491">arXiv:2312.11491</a> <span> [<a href="https://arxiv.org/pdf/2312.11491">pdf</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> <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"> Lithium niobate-enhanced laser photoacoustic spectroscopy </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Lin%2C+H">Haoyang Lin</a>, <a href="/search/physics?searchtype=author&query=Zhu%2C+W">Wenguo Zhu</a>, <a href="/search/physics?searchtype=author&query=Zhong%2C+Y">Yongchun Zhong</a>, <a href="/search/physics?searchtype=author&query=Tang%2C+J">Jieyuan Tang</a>, <a href="/search/physics?searchtype=author&query=Lu%2C+H">Huihui Lu</a>, <a href="/search/physics?searchtype=author&query=Yu%2C+J">Jianhui Yu</a>, <a href="/search/physics?searchtype=author&query=Zheng%2C+H">Huadan 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="2312.11491v1-abstract-short" style="display: inline;"> In this paper, the photoacoustic spectroscopy technique based on lithium niobate crystals is initially reported, to our knowledge.

Their photoluminescence blinking, however, hinders their practical use in many aspects. It has been shown that coupling QDs to plasmonic nanostructures may provide a viable way to suppress blinking. Nevertheless, the underlying mechanism of blinking suppression remains unclear and debated. Here, by deterministically coupling a single QD to a plasmonic nanocavity, we clarify the mechanism of blinking suppression, and demonstrate unprecedentedly bright emission from a single colloidal QD. In particular, we report for the first time that the coupled system exhibits nonblinking photoluminescence with blinking lifetime, which shows that the elimination of photoluminescence blinking originates from enhanced quantum yield of the charged states. We identify that the radiative decay rate is boosted from (48 ns)-1 to (0.7 ns)-1, which outcompetes Auger processes and enables similar quantum yields for charged and neutral excitons. Moreover, we demonstrate ultrabright photoluminescence of up to 17 million detected photons per second from a single QD. This work sheds new light on the goal of achieving ultrabright nonblinking QDs and may benefit a variety of QD-based applications. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2311.11560v1-abstract-full').style.display = 'none'; document.getElementById('2311.11560v1-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 November, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> November 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">17 pages; 3 figures;</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Nano Letters 24, 1761 (2024) </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2311.06019">arXiv:2311.06019</a> <span> [<a href="https://arxiv.org/pdf/2311.06019">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="Applied Physics">physics.app-ph</span> </div> </div> <p class="title is-5 mathjax"> Multi-dimensional vibration sensing and simultaneous self-homodyne optical transmission of single wavelength net 5.36 Tb/s signal using telecom 7-core fiber </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Tang%2C+J">Jianwei Tang</a>, <a href="/search/physics?searchtype=author&query=Li%2C+X">Xueyang Li</a>, <a href="/search/physics?searchtype=author&query=Yang%2C+B">Bang Yang</a>, <a href="/search/physics?searchtype=author&query=Cheng%2C+C">Chen Cheng</a>, <a href="/search/physics?searchtype=author&query=Hao%2C+Y">Yaguang Hao</a>, <a href="/search/physics?searchtype=author&query=Xu%2C+Y">Yifan Xu</a>, <a href="/search/physics?searchtype=author&query=Li%2C+J">Jiali Li</a>, <a href="/search/physics?searchtype=author&query=He%2C+Z">Zhixue He</a>, <a href="/search/physics?searchtype=author&query=Yang%2C+Y">Yanfu Yang</a>, <a href="/search/physics?searchtype=author&query=Hu%2C+W">Weisheng 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="2311.06019v1-abstract-short" style="display: inline;"> We present a high-capacity self-homodyne optical transmission system that enables simultaneously multidimensional vibration sensing based on a weakly-coupled 7-core fiber.

The film deposited at 440 $^{\circ}$C exhibited either poor crystallization or an amorphous structure; the film grown at 500 $^{\circ}$C contained both $尾$-$Ga_2O_3$ and $纬$-$Ga_2O_3$. A nominally phase-pure $尾$-$Ga_2O_3$ film was obtained at 530 $^{\circ}$C. Atomic-resolution scanning transmission electron microscopy (STEM) investigations of the $纬$-$Ga_2O_3$ film grown at 470 $^{\circ}$C revealed a high density of antiphase boundaries. A planar defect model developed for $纬$-$Al_2O_3$ was extended to explain the stacking sequences of the Ga sublattice observed in the STEM images of $纬$-$Ga_2O_3$. The presence of the 180$^{\circ}$ rotational domains and 90$^{\circ}$ rotational domains of $尾$-$Ga_2O_3$ inclusions within the $纬$-$Ga_2O_3$ matrix is discussed within the context of a comprehensive investigation of the epitaxial relationship between those two phases in the as-grown film at 470 $^{\circ}$C and the same film annealed at 600 $^{\circ}$C. The results led to the hypotheses that (i) incorporation of certain dopants including Si, Ge, Sn, Mg, Al, and Sc, into $尾$-$Ga_2O_3$, locally stabilizes the "$纬$-phase" and (ii) the site preference(s) for these dopants promotes the formation of the "$纬$-phase" and/or $纬$-$Ga_2O_3$ solid solutions. However, in the absence of such dopants, pure $纬$-$Ga_2O_3$ remains the least stable $Ga_2O_3$ polymorph, as indicated by its very narrow growth window, lower growth temperatures relative to other $Ga_2O_3$ polymorphs, and the largest calculated difference in Helmholtz free energy per formula unit between $纬$-$Ga_2O_3$ and $尾$-$Ga_2O_3$ than all other polymorphs. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2310.12493v2-abstract-full').style.display = 'none'; document.getElementById('2310.12493v2-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 October, 2023; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 19 October, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> October 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">The following article has been submitted to APL Materials</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2310.06144">arXiv:2310.06144</a> <span> [<a href="https://arxiv.org/pdf/2310.06144">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="Applied Physics">physics.app-ph</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"> Ions-induced Epitaxial Growth of Perovskite Nanocomposites for Highly Efficient Light-Emitting Diodes with EQE Exceeding 30% </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Xing%2C+Z">Zhaohui Xing</a>, <a href="/search/physics?searchtype=author&query=Du%2C+Q">Qing Du</a>, <a href="/search/physics?searchtype=author&query=Pang%2C+P">Peiyuan Pang</a>, <a href="/search/physics?searchtype=author&query=Jin%2C+G">Guangrong Jin</a>, <a href="/search/physics?searchtype=author&query=Liu%2C+T">Tanghao Liu</a>, <a href="/search/physics?searchtype=author&query=Shen%2C+Y">Yang Shen</a>, <a href="/search/physics?searchtype=author&query=Zhang%2C+D">Dengliang Zhang</a>, <a href="/search/physics?searchtype=author&query=Yu%2C+B">Bufan Yu</a>, <a href="/search/physics?searchtype=author&query=Liang%2C+Y">Yue Liang</a>, <a href="/search/physics?searchtype=author&query=Tang%2C+J">Jianxin Tang</a>, <a href="/search/physics?searchtype=author&query=Wang%2C+L">Lei Wang</a>, <a href="/search/physics?searchtype=author&query=Xing%2C+G">Guichuang Xing</a>, <a href="/search/physics?searchtype=author&query=Chen%2C+J">Jiangshan Chen</a>, <a href="/search/physics?searchtype=author&query=Ma%2C+D">Dongge Ma</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="2310.06144v2-abstract-short" style="display: inline;"> Metal halide perovskites, a class of cost-effective semiconductor materials, are of great interest for modern and upcoming display technologies that prioritize the light-emitting diodes (LEDs) with high efficiency and excellent color purity.

The prevailing approach to achieving efficient luminescence from pervoskites is enhancing exciton binding effect and confining carriers by reducing their dimensionality or grain size. However, splitting pervoskite lattice into smaller ones generates abundant boundaries in solid films and results in more surface trap states, needing exact passivation to suppress trap-assisted nonradiative losses. Here, an ions-induced heteroepitaxial growth method is employed to assembe perovskite lattices with different structures into large-sized grains to produce lattice-anchored nanocomposites for efficient LEDs with high color purity. This approach enables the nanocomposite thin films, composed of three-dimensional (3D) CsPbBr3 and its variant of zero-dimensional (0D) Cs4PbBr6, to feature significant low trap-assisted nonradiative recombination, enhanced light out-coupling with a corrugated surface, and well-balanced charge carrier transport. Based on the resultant 3D/0D perovskite nanocomposites, we demonstrate the perovskite LEDs achieving an remarkable external quantum efficiency of 31.0% at the emission peak of 521 nm with a narrow full width at half-maximum of only 18 nm. This research introduces a novel approach to the development of well-assembled nanocomposites for perovskite LEDs, demonstrating high efficiency comparable to that of state-of-the-art organic LEDs. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2310.06144v2-abstract-full').style.display = 'none'; document.getElementById('2310.06144v2-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 March, 2024; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 9 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/2310.05669">arXiv:2310.05669</a> <span> [<a href="https://arxiv.org/pdf/2310.05669">pdf</a>, <a href="https://arxiv.org/format/2310.05669">other</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="High Energy Physics - Experiment">hep-ex</span> </div> </div> <p class="title is-5 mathjax"> Transverse Emittance Reduction in Muon Beams by Ionization Cooling </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=The+MICE+Collaboration"> The MICE Collaboration</a>, <a href="/search/physics?searchtype=author&query=Bogomilov%2C+M">M.

However, high-brightness muon beams have not yet been produced. The main challenge for muon acceleration and storage stems from the large phase-space volume occupied by the beam, derived from the muon production mechanism through the decay of pions from proton collisions. Ionization cooling is the technique proposed to decrease the muon beam phase-space volume. Here we demonstrate a clear signal of ionization cooling through the observation of transverse emittance reduction in beams that traverse lithium hydride or liquid hydrogen absorbers in the Muon Ionization Cooling Experiment (MICE). The measurement is well reproduced by the simulation of the experiment and the theoretical model. The results shown here represent a substantial advance towards the realization of muon-based facilities that could operate at the energy and intensity frontiers. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2310.05669v2-abstract-full').style.display = 'none'; document.getElementById('2310.05669v2-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, 2023; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 9 October, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> October 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">23 pages and 5 figures</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Report number:</span> STFC-P-2023-004 </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2309.14982">arXiv:2309.14982</a> <span> [<a href="https://arxiv.org/pdf/2309.14982">pdf</a>, <a href="https://arxiv.org/format/2309.14982">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/10.1103/PhysRevLett.132.171001">10.1103/PhysRevLett.132.171001 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Experimental Limits on Solar Reflected Dark Matter with a New Approach on Accelerated-Dark-Matter-Electron Analysis in Semiconductors </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Zhang%2C+Z+Y">Z.

Models beyond the standard halo model describing DM accelerated by high energy celestial bodies are under intense examination as well. In this Letter, a velocity components analysis (VCA) method dedicated to swift analysis of accelerated DM-electron interactions via semiconductor detectors is proposed and the first HPGe detector-based accelerated DM-electron analysis is realized. Utilizing the method, the first germanium based constraint on sub-GeV solar reflected DM-electron interaction is presented with the 205.4 kg$\cdot$day dataset from the CDEX-10 experiment. In the heavy mediator scenario, our result excels in the mass range of 5$-$15 keV/$c^2$, achieving a 3 orders of magnitude improvement comparing with previous semiconductor experiments. In the light mediator scenario, the strongest laboratory constraint for DM lighter than 0.1 MeV/$c^2$ is presented. The result proves the feasibility and demonstrates the vast potential of the VCA technique in future accelerated DM-electron analyses with semiconductor detectors. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2309.14982v3-abstract-full').style.display = 'none'; document.getElementById('2309.14982v3-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 April, 2024; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 26 September, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> September 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">7 pages, 4 figures.

However, it remains challenging to develop a magnon-based logic due to the lack of efficient electrical manipulation of magnon transport. Here we present a magnon logic-in-memory device in a spin-source/multiferroic/ferromagnet structure, where multiferroic magnon modes can be electrically excited and controlled. In this device, magnon information is encoded to ferromagnetic bits by the magnon-mediated spin torque. We show that the ferroelectric polarization can electrically modulate the magnon spin-torque by controlling the non-collinear antiferromagnetic structure in multiferroic bismuth ferrite thin films with coupled antiferromagnetic and ferroelectric orders. By manipulating the two coupled non-volatile state variables (ferroelectric polarization and magnetization), we further demonstrate reconfigurable logic-in-memory operations in a single device. Our findings highlight the potential of multiferroics for controlling magnon information transport and offer a pathway towards room-temperature voltage-controlled, low-power, scalable magnonics for in-memory computing. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2309.14614v1-abstract-full').style.display = 'none'; document.getElementById('2309.14614v1-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 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/2309.07025">arXiv:2309.07025</a> <span> [<a href="https://arxiv.org/pdf/2309.07025">pdf</a>, <a href="https://arxiv.org/ps/2309.07025">ps</a>, <a href="https://arxiv.org/format/2309.07025">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"> A linear model of synergetic current drive with lower-hybrid wave and electron cyclotron wave </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Chen%2C+J+N">J.

In this model, the response function dominated by collisions in the presence of LHW is derived from the adjoint equations by using perturbation and Green-Function techniques, where the relativistic effect and the trapped effect are taken into account. The SCD efficiency is compared with the commonly used ECW current drive (ECCD) efficiency in the parameter space using our linear model. The results show two features of the synergy effect, One is that it is inclined to occurs at smaller $y = 2蠅_{c}/蠅$ with the fixed ECW parallel refractive index $n_{\parallel}$, and the other is that the threshold values of $y$, at which the synergy effect becomes sufficiently significant, shifts towards higher values with a decreasing $n_{\parallel}$. The quasilinear simulation on ECCD and SCD efficiency with a two-dimensional Fokker-Planck code are consistent with the results of the linear model in trends. Based on the linear SCD efficiency, criteria for the occurrence and the sufficient significance of the synergy effect are suggested, which indicate that the synergy effect is dependent on the power factor that quantifies the degree of the overlap of the two waves' quasilinear domains, the LHW power, and synergy electrons. The present work provides a method of quick matching and calculating of SCD with LHW and ECW, and may be important for the real-time application of the SCD in future reactors. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2309.07025v3-abstract-full').style.display = 'none'; document.getElementById('2309.07025v3-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 November, 2023; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 13 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/2309.05933">arXiv:2309.05933</a> <span> [<a href="https://arxiv.org/pdf/2309.05933">pdf</a>, <a href="https://arxiv.org/format/2309.05933">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="Accelerator Physics">physics.acc-ph</span> </div> </div> <p class="title is-5 mathjax"> Workshop on a future muon program at FNAL </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Corrodi%2C+S">S.

The Workshop on a future muon program at FNAL was held in March 2023 to discuss design studies for Mu2e-II, organizing efforts for the next generation muon facility, and identify synergies with other efforts (e.g., muon collider). Topics included high-power targetry, status of R&D for Mu2e-II, development of compressor rings, FFA and concepts for muon experiments (conversion, decays, muonium and other opportunities) at AMF.

This paper comprises a thorough summary of the CDEX-50 dark matter experiment, including an investigation of potential background sources and the development of a background model. Based on the baseline model, the projected sensitivity of weakly interacting massive particle (WIMP) is also presented. The expected background level within the energy region of interest, set to 2--2.5 keVee, is $\sim$0.01 counts keVee$^{-1}$ kg$^{-1}$ day$^{-1}$. At 90\% confidence level, the expected sensitivity to spin-independent WIMP-nucleon couplings is estimated to reach a cross-section of 5.1 $\times$ 10$^{-45}$ cm$^{2}$ for a WIMP mass of 5 GeV/c$^{2}$ with an exposure objective of 150 kg$\cdot$year and an analysis threshold of 160 eVee. This science goal will correspond to the most sensitive results for WIMPs with a mass of 2.2--8 GeV/c$^{2}$. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2309.01843v2-abstract-full').style.display = 'none'; document.getElementById('2309.01843v2-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 July, 2024; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 4 September, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> September 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">12 pages, 11 figures.

Instead of using the same Dirac equation involving four anti-commutative matrices for all such structure-less elementary particles, we consider in the first model the use of sixteen direct-product matrices of quaternions that are related to Diracs gamma matrices. This associative direct-product matrix model could not generate three fermion generations satisfying Einsteins mass-energy relation. We show that sedenion algebra contains five distinct quaternion sub-algebras and three octonion sub-algebras but with a common intersecting quaternion algebra. This model naturally leads to precisely three generations as each of the non-associative octonion sub-algebra leads to one fermion generation. Moreover, we demonstrate the use of basic sedenion. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2308.14768v2-abstract-full').style.display = 'none'; document.getElementById('2308.14768v2-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> 29 August, 2023; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 27 August, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> August 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">19 pages, 5 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/2308.08845">arXiv:2308.08845</a> <span> [<a href="https://arxiv.org/pdf/2308.08845">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="Atomic and Molecular Clusters">physics.atm-clus</span> </div> </div> <p class="title is-5 mathjax"> Efficient spectral broadening and few-cycle pulse generation with multiple thin water films </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Huang%2C+J">Jiacheng Huang</a>, <a href="/search/physics?searchtype=author&query=Lu%2C+X">Xiang Lu</a>, <a href="/search/physics?searchtype=author&query=Hu%2C+F">Feilong Hu</a>, <a href="/search/physics?searchtype=author&query=Long%2C+J">Jie Long</a>, <a href="/search/physics?searchtype=author&query=Tang%2C+J">Jiajun Tang</a>, <a href="/search/physics?searchtype=author&query=He%2C+L">Lixin He</a>, <a href="/search/physics?searchtype=author&query=Zhang%2C+Q">Qingbin Zhang</a>, <a href="/search/physics?searchtype=author&query=Lan%2C+P">Pengfei Lan</a>, <a href="/search/physics?searchtype=author&query=Lu%2C+P">Peixiang Lu</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="2308.08845v1-abstract-short" style="display: inline;"> High-energy, few-cycle laser pulses are essential for numerous applications in the fields of ultrafast optics and strong-field physics, due to their ultrafast temporal resolution and high peak intensity.

In this work, different from the traditional hollow-core fibers and multiple thin solid plates, we represent the first demonstration of the octave-spanning supercontinuum broadening by utilizing multiple ultrathin liquid films (MTLFs) as the nonlinear media. The continuum covers a range from 380 to 1050 nm, corresponding to a Fourier transform limit pulse width of 2.5 fs, when 35 fs Ti:sapphire laser pulse is applied on the MTLFs. The output pulses are compressed to 3.9 fs by employing chirped mirrors. Furthermore, a continuous high-order harmonic spectrum up to the 33rd order is realized by subjecting the compressed laser pulses to interact with Kr gas. The utilization of flowing water films eliminates permanent optical damage and enables wider and stronger spectrum broadening. Therefore, this MTLFs scheme provides new solutions for the generation of highly efficient femtosecond supercontinuum and nonlinear pulse compression, with potential applications in the fields of strong-field physics and attosecond science. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2308.08845v1-abstract-full').style.display = 'none'; document.getElementById('2308.08845v1-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 August, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> August 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">9 pages, 5 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/2307.11250">arXiv:2307.11250</a> <span> [<a href="https://arxiv.org/pdf/2307.11250">pdf</a>, <a href="https://arxiv.org/format/2307.11250">other</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> </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.131.055001">10.1103/PhysRevLett.131.055001 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Active Q-switched X-Ray Regenerative Amplifier Free-Electron Laser </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Tang%2C+J">Jingyi Tang</a>, <a href="/search/physics?searchtype=author&query=Zhang%2C+Z">Zhen Zhang</a>, <a href="/search/physics?searchtype=author&query=Morgan%2C+J">Jenny Morgan</a>, <a href="/search/physics?searchtype=author&query=Hemsing%2C+E">Erik Hemsing</a>, <a href="/search/physics?searchtype=author&query=Huang%2C+Z">Zhirong Huang</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="2307.11250v1-abstract-short" style="display: inline;"> Despite tremendous progress in x-ray free-electron laser (FEL) science over the last decade, future applications still demand fully coherent, stable x-rays that have not been demonstrated in existing X-ray FEL facilities.
