    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


    Figure (a) Hall conductance with decoherence coherence strength Гv change curve; Figure (b) Td spatial distribution, Td is used to describe semi-quantized chiral channels; Figures (c) and (d), Hall conductance and longitudinal conductance vs.


    Zhou Humian, phD student at the Center for Quantum Materials Science, School of Physics, Peking University, is the first author, and Professor Chen Chuixin and Professor Xie Xincheng of the School of Physical Science and Technology of Soochow University are co-corresponding authors
