Light-induced thermal noise \textit{anomaly} governed by quantum metric
Longjun Xiang, Lei Zhang, Jun Chen +3
Traditionally, thermal noise in electric currents, arising from thermal agitation, is expected to increase with temperature and disappear as approaches zero. Contrary to th…
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…
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…
Spin transport revealed by the spin quantum geometry
Longjun Xiang, Hao Jin, Jian Wang
We present the framework of \textit{spin quantum geometry}, which is fundamentally linked to the spin degree of freedom of Bloch electrons and incorporates both the spin quantum ge…
Equivalence of semiclassical and response theories for second-order nonlinear ac Hall effects
Jinxiong Jia, Longjun Xiang, Zhenhua Qiao +1
It has been known that the semiclassical theory and the response theory can equivalently give the Drude and the intrinsic anomalous Hall conductivities in the linear order of elect…
