Engineering topological phases in graphene systems

Prof Qian Niu (University of Texas, Austin/Peking University)
Mon, 03/09/2012 - 2:00pm to 3:00pm
S13-M01-11 (Physics Conference Room)
Event Type: 

This seminar is the first of two joint seminars, followed by Prof Shun-Qing Shen's "Topological Insulator: Dirac equation in condensed matter".


In this talk Prof Niu will discuss how to apply external conditions, such as Rashba and Zeeman coupling as well as interlayer bias, to induce bulk energy gaps at the Dirac points, and show what kind of topological phases can appear in the resulting insulator.

Bio sketch for Prof Qian Niu:

Qian Niu is a Trull Centennial Professor of Physics at The University of Texas at Austin, from which he is currently on leave to serve as the director of the International Center for Quantum Materials at Peking University. 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.
