Quantum geometric map of magnetotransport
Longjun Xiang, Jinxiong Jia, Fuming Xu +1
We propose a quantum geometric map for the magnetononlinear Hall effect (MNHE), the planar Hall effect (PHE), and the ordinary Hall effect (OHE). These magnetotransport phenomena o…
Quantum Geometric Entropy Production and Entropy Hall Effect
Longjun Xiang, Jinxiong Jia, Jian Wang
Quantum geometry, encoded in the Berry curvature and quantum metric, has unified diverse anomalous transport phenomena in solids, yet a microscopic quantum-geometric theory of entr…
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…
Nonlinear Magnetoelectric Edelstein Effect
Jinxiong Jia, Longjun Xiang, Zhenhua Qiao +1
The linear Edelstein effect is a cornerstone phenomenon in spintronics that describes the generation of spin magnetization in response to an applied electric field. Recent theoreti…
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…
