Author(s): Jiali Chen, Chaoxi Cui, Zhi-Ming Yu, Wei Jiang, and Yugui Yao The anomalous Hall conductivity in magnetic Weyl semimetals scales linearly with the momentum separation between Weyl nodes, establishing a geometric paradigm for three-dimensional Hall responses. Here, we discover an analogous phenomenon in the spin Hall effect: a quantized spin Hall conductivity (… [Phys. Rev. Lett. 137, 086301] Published Mon Aug 17, 2026
