The 337th forum: Topology and Geometry of Bloch Electrons
University of Texas at Austin
Qian Niu is a Trull Centennial Professor of Physics at The University of Texas at Austin. 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 obtained a B.S. from Peking University and a Ph.D. from the University of Washington at Seattle, and did postdoctoral work at the University of Illinois at Urbana-Champaign and the University of California at Santa Barbara before joining the faculty of UT Austin in 1990. He was granted a Blumberg Fellowship(1992-1993) and Outstanding Overseas Young Scientist(1999, Natural Science Foundation of China), and received NIST Precision Measurement Award(1992-1995).
The 2016 Nobel prize for physics was a grant celebration of our understanding of topological phases and transition, part of which dates back to pioneering work of David Thouless and his collaborators when I became a graduate student of him 36 years ago. I was fortunate to be able to wetness and even participate the development of this topological theory of Chern insulators at the beginning of my career. In this talk, I will give an `inside look' of the topological Chern numbers, not only from my personal perspective, but also concentrating on its physical content, the Berry curvatures, to see how such topological and geometrical concepts have transformed our view of solid state physics.
