Dissipationless Photovoltaic Spin Hall Effect from Spin-current Vorticity
Longjun Xiang, Jian Wang
Spin-current vorticity (SCV) can generate the linear magnetic spin Hall effect [\href{https://doi.org/10.1038/s41586-018-0853-0}{Nature \textbf{565}, 627 (2019)}], yet its role in…
Third-order intrinsic anomalous Hall effect as a transport fingerprint of altermagnets
Longjun Xiang, Hao Jin, Jian Wang
The intrinsic anomalous Hall effect (IAHE) provides a powerful transport fingerprint of quantum magnets, with its linear and second-order responses distinguishing ferromagnets and…
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…
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…
Tunable Giant Rashba-type Spin Splitting in PtSe/MoSe Heterostructure
Longjun Xiang, Youqi Ke, Qingyun Zhang
We report a giant Rashba-type spin splitting in two-dimensional heterostructure PtSe/MoSe with first-principles calculations. We obtain a large value of spin splitting ener…
