The investigation of the topological phase of matter has been a major subject in condensed matter physics. Among various topological phases, the quantum anomalous Hall (QAH) insulator with the spontaneous time-reversal symmetry breaking in the absence of external magnetic fields is especially interesting. The exploration of QAH states has always been limited to ferromagnetic systems. Here, we introduce an alternative scheme for realizing the QAH effect in nonmagnetic systems subject to circularly polarized light. We further realized our proposals in disordered systems with nonmagnetic dopping and heterobilayers of transition-metal dichalcogenides via numerical calculations.
