Unconventional Hall Effect in Gapless Superconductors: Transverse Supercurrent Converted from Normal Current
Miaomiao Wei, Longjun Xiang, Fuming Xu +2
A normal metallic system proximitized by a superconductor can exhibit a gapless superconducting state characterized by segmented Fermi surfaces, as confirmed experimentally. In suc…
Pseudo-Riemannian metric: a new perspective on the quantum realm
Miaomiao Wei, Longjun Xiang, Fuming Xu +2
As a fundamental concept in condensed matter physics, quantum geometry within the Riemannian metric elucidates various exotic phenomena, including the Hall effects driven by Berry…
Gauge invariant quantum transport theory for non-Hermitian systems
Miaomiao Wei, Bin Wang, Jian Wang
Gauge invariance is a fundamental principle that must be preserved in quantum transport. However, when a complex potential is incorporated into the Hamiltonian, we find that the cu…
Quantum intrinsic -odd spin Hall effect in altermagnets
Miaomiao Wei, Longjun Xiang, Fuming Xu +2
Drude weight, historically associated with the longitudinal Drude conductivity, can be generalized to describe the transverse or Hall component of the extrinsic conductivity tensor…
Bulk-boundary-transport correspondence of the second-order topological insulators
Yuxiong Long^§, Miaomiao Wei^§, Fuming Xu +1
The bulk-boundary correspondence of the second-order topological insulator (SOTI) has been well established, but a universal transport signature for open systems is still absent. F…
Gapless superconducting state and mirage gap in altermagnets
Miaomiao Wei, Longjun Xiang, Fuming Xu +3
The interplay between spin-orbit interaction (SOI) and magnetism produces interesting phenomena in superconductors. When a two-dimensional (2D) system with strong SOI is coupled to…
Quantum Fluctuation of the Quantum Geometric Tensor and its Manifestation as Intrinsic Hall Signatures in Time-Reversal Invariant Systems
Miaomiao Wei, Luyang Wang, Bin Wang +4
In time-reversal invariant systems, all charge Hall effects predicted so far are extrinsic effects due to the dependence on the relaxation time. We explore intrinsic Hall signature…
Remotely preparing optical Schrödinger cat states via homodyne detection in nondegenerate triple-photon spontaneous downconversion
Miaomiao Wei, Huatang Tan, Qiongyi He
Optical downconversion is a key resource for generating nonclassical states. Very recently, direct nondegenerate triple-photon spontaneous downconversion (NTPSD) with bright photon…
Quantum third-order nonlinear Hall effect of a four-terminal device with time-reversal symmetry
Miaomiao Wei, Longjun Xiang, Luyang Wang +2
The third-order nonlinear Hall effect induced by Berry-connection polarizability tensor has been observed in Weyl semimetals T-MoTe as well as T-TaIrTe. The experim…
Nonlinear Hall effect induced by internal Coulomb interaction and phase relaxation process in a four-terminal system with time-reversal symmetry
Miaomiao Wei, Bin Wang, Yunjin Yu +2
We numerically investigate the second-order nonlinear Hall transport properties of a four-terminal system with time-reversal symmetry and broken inversion symmetry. Within the none…
