摘要：

The quantum anomalous Hall effect (QAHE) exhibits an insulating bulk state with quantized edge transport within the band gap. However, in practical materials, the temperature at which quantized transport is observed in the QAHE is consistently lower than the band gap. Investigations into quantum transport theory offer new perspectives to these issues. In this talk, I will provide an overview of the transport theory of the QAHE, and then demonstrate that plateau transitions in the QAHE exhibit its characteristic topological properties. Next, I will introduce a Berry curvature splitting mechanism that facilitates the realization of the quantum anomalous phase. Additionally, I will discuss our exploration of the quantum anomalous layer Hall effect in magnetic topological insulator multilayers.
