v3.2.3
I will review the relativistic origin of spin orbit coupling and its quantum geometric nature, and then introduce three applications: orbital magnetism, anomalous Hall effect in noncollinear antiferromagnets, and multi polar anisotropy in collinear magnets.
Prof. Qian Niu obtained a B.S. from Peking University in 1981. He went to the University of Washington for graduate studies, and received his Ph.D. in physics in 1985. He was Sid W. Richardson Foundation Regents Chair in Physics at the University of Texas at Austin, USA before joining University of Science and Technology of China as a Distinguished Chair Professor in 2021. He has worked on the theories on quantum Hall effects, quasicrystals, ultracold atoms, spin transport, and graphene materials, with an emphasis on topological and geometric phase effects in quantum transport. He has published ~280 peer reviewed papers, including 84 in Physical Review Letters, 3 in Science, 5 in Nature and its subsidiaries, 1 each in Review of Modern Physics, Physics Today, and Physics World. These papers have generated over 33,000 citations (with an H index of 83). He is a Fellow of the American Physical Society.
