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…

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 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…
