SUMMARY:Experiments on Dirty Bosons\, Physics Department Colloquium\, 
 Brian DeMarco\, University of Illinois at Urbana-Champaign
DESCRIPTION:Ultra-cold atom gases trapped in an optical lattice are no
 w poised to make strong contributions to resolving outstanding questio
 ns in condensed matter physics.  In these experiments\, atom gases are
  cooled to temperatures below a millionth of a degree of absolute zero
  and confined in a crystal of light.  I will talk about how we are usi
 ng this system to simulate models relevant to dirty superconductors.  
 I will report on the first experiments using optical lattices that inc
 lude fine-grained disorder\, including the observation of a disorder-i
 nduced superfluid-to-insulator transition.
