Xie Xincheng's research group and collaborators in the School of Physics have made important progress in the research of semi-quantized Hall conductive transport theory in semi-magnetic topological insulators

Recently, Xie Xincheng's research group and collaborators at the Center for Quantum Materials Science, School of Physics, Peking University, proposed a transport theory

Macroscopic quantum phenomena such as the fractional quantum Hall effect and the integer quantum Hall effect are an overall quantum phenomenon

Starting from the heterojunction experimental system of semi-magnetic topological insulators, Xie Xincheng's research group and collaborators systematically studied the transport properties of the Dirac cone on the surface of the semi-magnetic topological insulator, revealing the importance
