Hsin Lin is a Postdoctoral Research Associate in Professor Bansil’s group in the Department of Physics at Northeastern University, where he received his Ph.D. in 2008. He obtained his M.S. degree from National Tsing Hua University and B.S. degree from National Taiwan University. His research focuses on the electronic structure and spectroscopy of exotic quantum states of matter such as topological insulators, high temperature superconductors, and colossal magnetoresistance materials. Based on first-principles calculations and realistic tight-binding modeling, he is working to elucidate generalized matrix element effects in various spectroscopies.
The energy-momentum relationship of electrons on the surface of an ideal topological insulator forms a cone, which, when warped, can lead to unusual phenomena such as enhanced interference around defects and a magnetically ordered exotic surface.
