Light‐Induced Quantum Anomalous Hall Effect on the 2D Surfaces of 3D Topological Insulators

Light‐Induced Quantum Anomalous Hall Effect on the 2D Surfaces of 3D Topological Insulators

Abstract Quantum anomalous Hall (QAH) effect generates quantized electric charge Hall conductance without external magnetic field. It requires both nontrivial band topology and time‐reversal symmetry (TRS) breaking. In most cases, one can break the TRS of time‐reversal invariant topological material...
