Three-dimensional quantum anomalous Hall effect in Weyl semimetals
Zhi-Qiang Zhang, Yu-Hang Li, Ming Lu +4
The quantum anomalous Hall effect (QAHE) is a quantum phenomenon in which a two-dimensional system exhibits a quantized Hall resistance in the absence of magnetic field, wh…
Measurement of the Chern Number for Non-Hermitian Chern Insulators
