SUMMARY:Topological Phases in Correlated Materials\, Physics Departmen
 t Colloquium\, Yong-Baek Kim\, University of Toronto
DESCRIPTION:Recently there have been significant theoretical and exper
 imental efforts to understand and identify the so-called topological p
 hases of matter in interacting electron systems. These topological pha
 ses may be characterized by different kinds of topological properties 
 such as non-trivial edge/surface states and/or unusual elementary exci
 tations in the bulk or surface. Notable examples include quantum spin 
 liquids\, topological insulators\, and other closely related phases.  
 One of the main challenges is to come up with theoretical criteria tha
 t can be used to identify or predict correlated materials that hold pr
 omise for the emergence of such topological phases. We discuss recent 
 theoretical and experimental developments in this direction\, along wi
 th a brief introduction to some of the proposed topological phases. In
  particular\, we focus on correlated materials with strong spin-orbit 
 coupling and/or near a metal-insulator transition.
