1. Topological insulators, Joel Moore

Tutorial Description
Topological insulators are new states of matter which have a gap in the bulk and robust metallic surface states on the boundary. In recent years, time-reversal invariant topological insulators have been theoretically predicted and experimentally realized in several materials including HgTe quantum wells, Bi1-xSb¬x alloys, Bi2Te3 and Bi2Se3 crystals, etc.

The surface states of topological insulators are protected by topological properties of the bulk, which behaves like massless relativistic particles. As topological nontrivial states of matter, topological insulators have various unique signatures, such as topological magneto-electric effect and a novel realization of “Majorana fermions” which are non-Abelian anyons. The research on topological insulators is experiencing an explosive growth now, because of both fundamental interests and potential applications ranging from spintronics to quantum computation.

The goal of this tutorial is to provide an introduction to the basic concepts about topological insulators, and an overview of the recent theoretical and experimental developments in this field.
