Intrinsic gyrotropic magnetic current from Zeeman quantum geometry
Longjun Xiang, Jinxiong Jia, Fuming Xu +2
Quantum geometric tensor (QGT), which is usually obtained by evaluating the quantum distance between Bloch states parametrized by momentum, plays a key role in exploring the exotic…
Classification of spin Hall effect in two-dimensional systems
Longjun Xiang, Fuming Xu, Luyang Wang +1
Physical properties such as the conductivity are usually classified according to the symmetry of the underlying system using Neumann's principle, which gives an upper bound for the…
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…
Linear displacement current solely driven by the quantum metric
Longjun Xiang, Bin Wang, Yadong Wei +2
Quantum metric and Berry curvature are the real part and imaginary part of the quantum geometric tensor, respectively. The T-odd (T: time-reversal) nonlinear Hall effect driven by…
Quantifying the photocurrent fluctuation in quantum materials by shot noise
Longjun Xiang, Hao Jin, Jian Wang
The DC photocurrent can detect the topology and geometry of quantum materials without inversion symmetry. Herein, we propose that the DC shot noise (DSN), as the fluctuation of pho…
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…
