Disorder induced time-reversal-odd nonlinear spin and orbital Hall effects
Ruda Guo, Yi Liu, Cong Xiao +1
We develop a theory for the second-order time-reversal-odd (-odd) angular-momentum current, incorporating both spin and orbital components. We reveal that besides spin…
Symplectic connection third-order Hall effect in a room-temperature ferromagnet
Yu Cao, Xukun Feng, Yiming Guo +18
Third-order nonlinear Hall effects (THE) have recently attracted considerable experimental interest as powerful probes for quantum geometric properties in emergent quantum material…
Electron Dynamics Reconstruction and Nontrivial Transport by Acoustic Waves
Zi-Qian Zhou, Zhi-Fan Zhang, Cong Xiao +2
Surface acoustic waves (SAWs) become a popular driving source in modern condensed matter physics, but most existing theories simplify them as electric fields and ignore the non-uni…
Eccentricity valley Hall effect
Jin Cao, Shen Lai, Cong Xiao +2
Valleytronics harnesses the valley degree of freedom -- energy-degenerate extrema in the electronic band structure -- for information storage and processing. Valley Hall effect (VH…
