Light-induced quantum anomalous Hall effect on the 2D surfaces of 3D topological insulators
Haowei Xu, Jian Zhou, Ju Li
Quantum anomalous Hall (QAH) effect generates quantized electric charge Hall conductance without external magnetic field. It requires both nontrivial band topology and time-reversa…
