SUMMARY:Topological insulators and topological superconductors\, Physi
 cs Department Colloquium\, Shoucheng Zhang\, Stanford University
DESCRIPTION:Recently\, a new class of topological states has been theo
 retically predicted and experimentally observed. The topological insul
 ators have an insulating gap in the bulk\, but have topologically prot
 ected edge or surface states due to the time reversal symmetry. Simila
 rly\, topological superconductors or superfluids have novel edge or su
 rface states consisting of Majorana fermions. In this talk\, I shall r
 eview the recent theoretical and experimental progress in the field\, 
 and focus on a number of outstanding issues\, including the quantized 
 anomalous Hall effect\, quantized magneto-electric effect\, the topolo
 gical Mott insulators and the search for topological superconductors a
 nd Majorana fermions.
