Comet Calendar Event Details
From Topological Insulators to Majorana Fermions
Wednesday, Jan 29
4 p.m. - 5:15 p.m. Location: SLC 1.102

Dr. Zhang Fan, Department of Physics, University of Pennsylvania

 

The discovery of topological insulators has created a revolution in condensed matter science that has far ranging implications over coming decades. I will introduce a simplest way to understand the “periodic table” for topological phases, and apply these ideas to semimetals, insulators, and superconductors. In the superconductor case, a Majorana Kramers pair may appear on the boundary and induces unprecedented fractional Josephson effects. These effects indicate the existence of a “periodic building” for topological phases, with the aforementioned table being its ground floor. Strong connections will be made to ongoing experiments and related topics.
