Depairing critical current density and the vortex-free state in FeSe nanobridges
Yue Sun, Yuling Xiang, Zhixiang Shi +1
The depairing limit and the vortex-free state in a superconductor is crucial for both the study of supercurrent related physics and the application eliminating noise linked to vort…
Boost of critical current density near quantum critical points in FeSe-Based superconductors with two superconducting domes
Wei Wei, Qiang Hou, Jiajia Feng +10
Recent studies have identified two superconducting domes in FeSe-based superconductors. It was discovered that each dome is accompanied by a distinct nematic quantum critical point…
Impact of Disorder on the Superconducting Properties and BCS-BEC Crossover in FeSe Single Crystals
Jianping Fu, Yue Sun, Jingting Chen +2
We investigate the crystal structure, transport properties and specific heat in five selected FeSe single crystals containing different amounts of disorder. Transport measurements…
Observation of Uniform Supercurrent Flow in Polycrystalline K-doped Ba122 by Combined Magneto-optical Imaging and Finite-element Modeling
Shota Ishiwata, Sunseng Pyon, Tsuyoshi Tamegai +2
Macroscopic current uniformity in a (Ba,K)Fe2As2 bulk sample produced by a process that demonstrated high trapped magnetic fields was evaluated through a comparative experimental a…
Effects of disorder on the quantum transport properties in topologically nontrivial metal PbTaSe
Longfei Sun, Yue Sun, Qiang Hou +5
Weak antilocalization (WAL), an increase in the electrical conductivity at low temperatures associated with the suppression of electron localization due to quantum interference eff…
Multiple magnetic orders discovered in the superconducting state of EuFe(AsP)
Nan Zhou, Yue Sun, Ivan S. Veshchunov +13
The interplay between superconductivity and magnetism is an important subject in condensed matter physics. EuFeAs-based iron pnictides could offer an interesting platea…
