In this work, we demonstrate the promise of topological excitonic insulators for identification due to their unique bulk-edge correspondence, as illustrated by the LiFe$X$ ($X$ = S, Se, and Te) family. First-principles Bethe-Salpeter equation calculations reveal excitonic instabilities in these spin-orbit coupling quantum anomalous Hall insulators. Effective Hamiltonian analyses indicate that spontaneous exciton condensation does not disrupt the gapless edge state but reconstructs the bulk-gap to be almost independent of the spin-orbit coupling strength. This change in the bulk-edge correspondence can be experimentally inspected by angle-resolved photoelectron spectroscopy or electron compressibility measurements, providing observational evidence for the identification of topological excitonic insulators. Moreover, exciton condensation raises the critical temperature of the topological nontrivial phase above room temperature. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2412.14600v1-abstract-full').style.display = 'none'; document.getElementById('2412.14600v1-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, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> December 2024. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2407.13084">arXiv:2407.13084</a> <span> [<a href="https://arxiv.org/pdf/2407.13084">pdf</a>, <a href="https://arxiv.org/ps/2407.13084">ps</a>, <a href="https://arxiv.org/format/2407.13084">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Strongly Correlated Electrons">cond-mat.str-el</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Materials Science">cond-mat.mtrl-sci</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/10.1088/1367-2630/ad8955">10.1088/1367-2630/ad8955 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> One-Dimensional Magnetic Excitonic Insulators </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/cond-mat?searchtype=author&query=Liu%2C+J">Jing Liu</a>, <a href="/search/cond-mat?searchtype=author&query=Qu%2C+H">Hongwei Qu</a>, <a href="/search/cond-mat?searchtype=author&query=Li%2C+Y">Yuanchang Li</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="2407.13084v1-abstract-short" style="display: inline;"> Dimensionality significantly affects exciton production and condensation.

Despite the report of excitonic instability in one-dimensional materials, it remains unclear whether these spontaneously produced excitons can form Bose-Einstein condensates. In this work, we first prove statistically that one-dimensional condensation exists when the spontaneously generated excitons are thought of as an ideal neutral Bose gas, which is quite different from the inability of free bosons to condense. We then derive a general expression for the critical temperature in different dimensions and find that the critical temperature increases with decreasing dimension. We finally predict by first-principles $GW$-BSE calculations that experimentally accessible single-chain staircase Scandocene and Chromocene wires are an antiferromagnetic spin-triplet excitonic insulator and a ferromagnetic half-excitonic insulator, respectively. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2407.13084v1-abstract-full').style.display = 'none'; document.getElementById('2407.13084v1-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">Report number:</span> https://iopscience.iop.org/article/10.1088/1367-2630/ad8955 </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> New J.

However our first-principles study of monolayer ferroelectric TiOCl$_2$ shows that this is not always the case. We find that ferroelectric polarization tends to weaken exciton binding but enhance exciton lifetime. This stems from the different effects of the induced built-in electric field and structural distortion by the spontaneous polarization: the former always destabilizes or even dissociates the exciton while the latter leads to a relaxation of the selection rule and activates excitons that are otherwise not optically active. Their combined effect leads to a halving of the exciton binding energy but a substantial increase in lifetime by 40 times. Our results deepen the understanding of the interaction of light with ferroelectric materials and provide new insights into the use of ferroelectricity to control exciton dynamics. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2305.16711v1-abstract-full').style.display = 'none'; document.getElementById('2305.16711v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 26 May, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> May 2023. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> PRB 107, 235407 (2023) </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2204.14238">arXiv:2204.14238</a> <span> [<a href="https://arxiv.org/pdf/2204.14238">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> </div> </div> <p class="title is-5 mathjax"> Crystallographic effects on transgranular chloride-induced stress corrosion crack propagation of arc welded austenitic stainless steel </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/cond-mat?searchtype=author&query=Qu%2C+H+J">Haozheng J.

Schmid and Taylor factor mismatches across grain boundaries (GBs) reveal that cracks propagate either from a hard to soft grain, which can be explained merely by mechanical arguments, or soft to hard grain. In the latter case, finite element analysis reveals that TGCISCC will arrest at GBs without sufficient mechanical stress, favorable crystallographic orientations, or crack tip corrosion. GB type does not play a significant role in determining TGCISCC cracking behavior nor susceptibility. TGCISCC crack behaviors at GBs are discussed in the context of the competition between mechanical, crystallographic, and corrosion factors. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2204.14238v1-abstract-full').style.display = 'none'; document.getElementById('2204.14238v1-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 April, 2022; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> April 2022. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2203.16310">arXiv:2203.16310</a> <span> [<a href="https://arxiv.org/pdf/2203.16310">pdf</a>, <a href="https://arxiv.org/format/2203.16310">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Mesoscale and Nanoscale Physics">cond-mat.mes-hall</span> </div> </div> <p class="title is-5 mathjax"> Hybrid magnonics for short-wavelength spin waves facilitated by a magnetic heterostructure </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/cond-mat?searchtype=author&query=Inman%2C+J">Jerad Inman</a>, <a href="/search/cond-mat?searchtype=author&query=Xiong%2C+Y">Yuzan Xiong</a>, <a href="/search/cond-mat?searchtype=author&query=Bidthanapally%2C+R">Rao Bidthanapally</a>, <a href="/search/cond-mat?searchtype=author&query=Louis%2C+S">Steven Louis</a>, <a href="/search/cond-mat?searchtype=author&query=Tyberkevych%2C+V">Vasyl Tyberkevych</a>, <a href="/search/cond-mat?searchtype=author&query=Qu%2C+H">Hongwei Qu</a>, <a href="/search/cond-mat?searchtype=author&query=Sklenar%2C+J">Joseph Sklenar</a>, <a href="/search/cond-mat?searchtype=author&query=Novosad%2C+V">Valentine Novosad</a>, <a href="/search/cond-mat?searchtype=author&query=Li%2C+Y">Yi Li</a>, <a href="/search/cond-mat?searchtype=author&query=Zhang%2C+X">Xufeng Zhang</a>, <a href="/search/cond-mat?searchtype=author&query=Zhang%2C+W">Wei Zhang</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2203.16310v1-abstract-short" style="display: inline;"> Recent research on hybrid magnonics has been restricted by the long magnon wavelengths of the ferromagnetic resonance modes.

The coupling between magnon modes in the two magnetic layers, i.e., the uniform mode in Permalloy (Py) and the perpendicular standing spin waves (PSSWs) in YIG, serves as an effective means for exciting short-wavelength PSSWs, which is further hybridized with the photon mode of the microwave resonator. The demonstrated magnon-photon coupling approaches the superstrong coupling regime, and can even be achieved near zero bias field. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2203.16310v1-abstract-full').style.display = 'none'; document.getElementById('2203.16310v1-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 March, 2022; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> March 2022. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">6 pages, 4 figures</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2203.16303">arXiv:2203.16303</a> <span> [<a href="https://arxiv.org/pdf/2203.16303">pdf</a>, <a href="https://arxiv.org/format/2203.16303">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> </div> </div> <p class="title is-5 mathjax"> Tunable magnetically induced transparency spectra in magnon-magnon coupled Y3Fe5O12/permalloy bilayers </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/cond-mat?searchtype=author&query=Xiong%2C+Y">Yuzan Xiong</a>, <a href="/search/cond-mat?searchtype=author&query=Inman%2C+J">Jerad Inman</a>, <a href="/search/cond-mat?searchtype=author&query=Li%2C+Z">Zhengyi Li</a>, <a href="/search/cond-mat?searchtype=author&query=Xie%2C+K">Kaile Xie</a>, <a href="/search/cond-mat?searchtype=author&query=Bidthanapally%2C+R">Rao Bidthanapally</a>, <a href="/search/cond-mat?searchtype=author&query=Sklenar%2C+J">Joseph Sklenar</a>, <a href="/search/cond-mat?searchtype=author&query=Li%2C+P">Peng Li</a>, <a href="/search/cond-mat?searchtype=author&query=Louis%2C+S">Steven Louis</a>, <a href="/search/cond-mat?searchtype=author&query=Tyberkevych%2C+V">Vasyl Tyberkevych</a>, <a href="/search/cond-mat?searchtype=author&query=Qu%2C+H">Hongwei Qu</a>, <a href="/search/cond-mat?searchtype=author&query=Xiao%2C+Z">Zhili Xiao</a>, <a href="/search/cond-mat?searchtype=author&query=Kwok%2C+W+K">Wai K.

In this work, we experimentally demonstrate a tunable MIT effect in the Y3Fe5O12(YIG)/Permalloy(Py) magnon-magnon coupled system via changing the magnetic field orientations. By probing the magneto-optic effects of Py and YIG, we identify clear features of MIT spectra induced by the mode hybridization between the uniform mode of Py and the perpendicular standing spin-wave modes of YIG. By changing the external magnetic field orientations, we observe a tunable coupling strength between the YIG's spin-wave modes and the Py's uniform mode, upon the application of an out-of-plane magnetic field. This observation is theoretically interpreted by a geometrical consideration of the Py and YIG magnetization under the oblique magnetic field even at a constant interfacial exchange coupling. Our findings show high promise for investigating tunable coherent phenomena with hybrid magnonic platforms. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2203.16303v1-abstract-full').style.display = 'none'; document.getElementById('2203.16303v1-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 March, 2022; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> March 2022. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">10 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/2202.08093">arXiv:2202.08093</a> <span> [<a href="https://arxiv.org/pdf/2202.08093">pdf</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Mesoscale and Nanoscale Physics">cond-mat.mes-hall</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Materials Science">cond-mat.mtrl-sci</span> <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"> High-performance and Low-power Transistors Based on Anisotropic Monolayer $尾$-TeO$_2$ </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/cond-mat?searchtype=author&query=Guo%2C+S">Shiying Guo</a>, <a href="/search/cond-mat?searchtype=author&query=Qu%2C+H">Hengze Qu</a>, <a href="/search/cond-mat?searchtype=author&query=Zhou%2C+W">Wenhan Zhou</a>, <a href="/search/cond-mat?searchtype=author&query=Yang%2C+S+A">Shengyuan A.

Inspired by the successful fabrication of 2D $尾$-TeO$_2$ and the high on/off ratio and high air-stability of fabricated field effect transistors (FETs) [Nat. Electron. 2021, 4, 277], we provide a comprehensive investigation of the electronic structure of monolayer $尾$-TeO$_2$ and the device performance of sub-10 nm metal oxide semiconductors FETs (MOSFETs) based on this material. The anisotropic electronic structure of monolayer $尾$-TeO$_2$ plays a critical role in the anisotropy of transport properties for MOSFETs. We show that the 5.2-nm gate-length n-type MOSFET holds an ultra-high on-state current exceeding 3700 渭A/渭m according to International Roadmap for Devices and Systems (IRDS) 2020 goals for high-performance devices, which is benefited by the highly anisotropic electron effective mass. Moreover, monolayer $尾$-TeO$_2$ MOSFETs can fulfill the IRDS 2020 goals for both high-performance and low-power devices in terms of on-state current, sub-threshold swing, delay time, and power-delay product. This study unveils monolayer $尾$-TeO$_2$ as a promising candidate for ultra-scaled devices in future nanoelectronics. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2202.08093v1-abstract-full').style.display = 'none'; document.getElementById('2202.08093v1-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 February, 2022; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> February 2022. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">21 pages, 6 figures</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2101.11044">arXiv:2101.11044</a> <span> [<a href="https://arxiv.org/pdf/2101.11044">pdf</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Mesoscale and Nanoscale Physics">cond-mat.mes-hall</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Materials Science">cond-mat.mtrl-sci</span> </div> <div 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.124.187701">10.1103/PhysRevLett.124.187701 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Voltage-controlled antiferromagnetism in magnetic tunnel junctions </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/cond-mat?searchtype=author&query=Xu%2C+M">Meng Xu</a>, <a href="/search/cond-mat?searchtype=author&query=Li%2C+M">Mingen Li</a>, <a href="/search/cond-mat?searchtype=author&query=Khanal%2C+P">Pravin Khanal</a>, <a href="/search/cond-mat?searchtype=author&query=Habiboglu%2C+A">Ali Habiboglu</a>, <a href="/search/cond-mat?searchtype=author&query=Insana%2C+B">Blake Insana</a>, <a href="/search/cond-mat?searchtype=author&query=Xiong%2C+Y">Yuzan Xiong</a>, <a href="/search/cond-mat?searchtype=author&query=Peterson%2C+T">Thomas Peterson</a>, <a href="/search/cond-mat?searchtype=author&query=Myers%2C+J+C">Jason C.

The system exhibits a rich and synergistic parameter space because of the ability to control individual photonic, electronic, and magnonic components. Taking advantage of the spin wave dispersion of YIG, the frequency self-generation as well as the related nonlinear processes become sensitive to the external magnetic field. Besides being known as a narrowband filter and a delay element, the YIG delayline possesses spin wave modes that can be controlled to mix with the optoelectronic modes to generate higher-order harmonic beating modes.

The measurement is achieved via a heterodyne detection of the coupled magnetization dynamics using a single wavelength that probes the magneto-optical Kerr and Faraday effects of Py and YIG, respectively. Clear features of the MIT effect are evident from the deeply modulated ferromagnetic resonance of Py due to the perpendicular-standing-spin-wave of YIG. We develop a phenomenological model that nicely reproduces the experimental results including the induced amplitude and phase evolution caused by the magnon-magnon coupling. Our work offers a new route towards studying phase-resolved spin dynamics and hybrid magnonic systems. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1912.13407v2-abstract-full').style.display = 'none'; document.getElementById('1912.13407v2-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 July, 2020; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 31 December, 2019; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> December 2019. </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">16 pages, 3 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/1901.01923">arXiv:1901.01923</a> <span> [<a href="https://arxiv.org/pdf/1901.01923">pdf</a>, <a href="https://arxiv.org/format/1901.01923">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Mesoscale and Nanoscale Physics">cond-mat.mes-hall</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Materials Science">cond-mat.mtrl-sci</span> </div> <div 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/PhysRevApplied.11.034047">10.1103/PhysRevApplied.11.034047 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Simultaneous Optical and Electrical Spin-Torque Magnetometry with Stroboscopic Detection of Spin-Precession Phase </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/cond-mat?searchtype=author&query=Li%2C+Y">Yi Li</a>, <a href="/search/cond-mat?searchtype=author&query=Saglam%2C+H">Hilal Saglam</a>, <a href="/search/cond-mat?searchtype=author&query=Zhang%2C+Z">Zhizhi Zhang</a>, <a href="/search/cond-mat?searchtype=author&query=Bidthanapally%2C+R">Rao Bidthanapally</a>, <a href="/search/cond-mat?searchtype=author&query=Xiong%2C+Y">Yuzan Xiong</a>, <a href="/search/cond-mat?searchtype=author&query=Pearson%2C+J+E">John E.

However, the detection and manipulation of spin precession phases remain a major challenge for advanced spintronic functionalities. By using simultaneous electrical and optical detection, we demonstrate the direct measurement of the precession phase of Permalloy ferromagnetic resonance driven by the spin-orbit torques from adjacent heavy metals. The spin Hall angle of the heavy metals can be independently determined from concurrent electrical and optical signals. The stroboscopic optical detection also allows spatially measuring local spin-torque parameters and the induced ferromagnetic resonance with comprehensive amplitude and phase information. Our study offers a route towards future advanced characterizations of spin-torque oscillators, magnonic circuits, and tunnelling junctions, where measuring the current-induced spin dynamics of individual nanomagnets are required. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1901.01923v1-abstract-full').style.display = 'none'; document.getElementById('1901.01923v1-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 January, 2019; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> January 2019. </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, 9 figures</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Phys.

Material inhomogeneity (it can be characterized well by the dispersion of elastic modulus) is the internal factor of dispersions of fatigue properties and the dispersion of the load is the external factor. In this paper, according to theoretical derivation and preliminary experiments verification, the following relationships between dispersions of fatigue properties and dispersions of static mechanical properties of a material are obtained: the dispersion of fatigue life is n (the fatigue index) times of the sum of the dispersion of elastic modulus and the dispersion of the load. The corresponding dispersion of fatigue life is a decreasing function of the given fatigue strength in the stage of high cycle fatigue; P-S curve (the probability statistical distribution of fatigue strength) under the given fatigue life cannot be directly by test, but P-S curve can be obtained on the bias of P-N curve (the probability statistical distribution of fatigue life), and the corresponding dispersion of fatigue strength is a decreasing function of the given fatigue life. On bias of conclusions above, not only the inhomogeneity of material but also the dispersion of the load needs to be considered in the fatigue design, especially in high cycle fatigue design. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1610.07933v1-abstract-full').style.display = 'none'; document.getElementById('1610.07933v1-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 October, 2016; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> October 2016. </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, 7 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/1301.1266">arXiv:1301.1266</a> <span> [<a href="https://arxiv.org/pdf/1301.1266">pdf</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Chemical Physics">physics.chem-ph</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Mesoscale and Nanoscale Physics">cond-mat.mes-hall</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Materials Science">cond-mat.mtrl-sci</span> </div> <div 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/10.1557/opl.2013.913">10.1557/opl.2013.913 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Flexible fiber batteries for applications in smart textiles </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/cond-mat?searchtype=author&query=Qu%2C+H">Hang Qu</a>, <a href="/search/cond-mat?searchtype=author&query=Bourgeois%2C+J">Jean-Pierre Bourgeois</a>, <a href="/search/cond-mat?searchtype=author&query=Rolland%2C+J">Julien Rolland</a>, <a href="/search/cond-mat?searchtype=author&query=Vlad%2C+A">Alexandru Vlad</a>, <a href="/search/cond-mat?searchtype=author&query=Gohy%2C+J">Jean-Fran莽ois Gohy</a>, <a href="/search/cond-mat?searchtype=author&query=Skorobogatiy%2C+M">Maksim Skorobogatiy</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="1301.1266v1-abstract-short" style="display: inline;"> Here we discuss two alternative approaches for building flexible batteries for applications in smart textiles.
