Quantized Spin-Hall Conductivity in Altermagnet FeTeO with Mirror-Spin Coupling
Run-Wu Zhang, Chaoxi Cui, Yang Wang +3
Due to spin-orbit coupling (SOC), crucial for the quantum spin Hall (QSH) effect, a quantized spin-Hall conductivity has not yet been reported in QSH insulators and other realistic…

Unconventional topological Weyl-dipole phonon
Jianhua Wang, Yang Wang, Feng Zhou +5
A pair of Weyl points (WPs) with opposite Chern numbers can exhibit an additional higher-order topological charge, giving rise to the formation of a Weyl di…
