Magnetoelectric Bulk Photovoltaic Effect in Centrosymmetric Solids
Longjun Xiang, Fuming Xu, Lei Zhang +1
It is commonly believed that a bulk photovoltaic current requires broken spatial inversion symmetry. However, in this work, we demonstrate that dc photocurrents can arise in centro…

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…
