When a sufficiently strong magnetic field is applied to a twodimensional electron gas,it will drive the electrons into quantized states,known as the Landau levels.The transport properties of such a system are best man...

Recently, the magnetic topological insulator(TI) MnBi2Te4 emerged as a competitive platform to realize quantum anomalous Hall(QAH) states. We report a Berry curvature splitting mechanism to realize the QAH effect in t...
