Light-induced Andreev phase coherence and tunneling Hall effect in semi-Dirac systems
W. Zeng
We theoretically investigate the charge transport in a normal metal/normal metal/superconductor junction based on semi-Dirac materials. It is shown that off-resonant circularly pol…
Strong correlation between -linear magnetoresistance and strange metal in FeSe superconductor
Xinyue Wang, Yue Sun, Wei Wei +4
In strange metals, a strong and anomalous scattering effect exists and increases linearly with temperature. In FeSe, we observed that the temperature dependence of resistivity exhi…
Pairing phase diagram for electron-doped cuprates in the square-lattice Hubbard model
Zhangkai Cao, Shuning Tan, Ji Liu +4
Motivated by significant discrepancies between experimental observations of electron-doped cuprates and numerical results of the Hubbard model, we investigate the role of nearest-n…
Floquet engineering of point-gapped topological superconductors
Xiang Ji, Hao Geng, Naeem Akhtar +1
Non-Hermitian systems exhibit two distinct topological classifications based on their gap structure: line-gap and point-gap topologies. Although point-gap topology is intrinsic to…
Bulk and surface Dirac states accompanied by two superconducting domes in FeSe-based superconductors
Qiang Hou, Wei Wei, Xin Zhou +8
Recent investigations of FeSe-based superconductors have revealed the presence of two superconducting domes, and suggest possible distinct pairing mechanisms. Two superconducting d…
Transverse Josephson diode effect in tilted Dirac systems
W. Zeng
We theoretically study the transverse charge transport in Josephson junctions based on the tilted Dirac materials with valley-dependent gaps. It is shown that a finite tilt-assiste…
