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…
Lindbladian Phase Geometry and Hall Transport in Open Bloch Systems
Zhihao Jiang, Longjun Xiang, Jian Wang
Quantum geometry underlies a wide range of transport phenomena in Bloch systems. How quantum-geometric transport is modified when Bloch electrons are coupled to an environment, how…
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…
Curvature-Flux Representation of Local Dirac-Node Topology from Non-Hermitian Zeeman Quantum Geometry
Rongjie Cui, Longjun Xiang, Fuming Xu +1
Local Dirac-node topology is usually described by a winding number or Berry phase, whereas curvature-flux formulations are commonly associated with global band topology. Here we sh…
Linear thermal noise induced by Berry curvature dipole in a four-terminal system
Wenyu Chen, Miaomiao Wei, Yunjin Yu +2
In this work, we numerically investigate linear thermal noise in a four-terminal system with a finite Berry curvature dipole (BCD) using the nonequilibrium Green's function formali…
