SUMMARY:Influence of Thermal Order Parameter Fluctuations on the Spectral 
 Function of 2D Superconductors - Prof. Alexei Tsvelik\, Brookhaven Nationa
 l Laboratory\, USA
DTSTART:20100226T141500Z

CONTACT:Joe Bhaseen
DESCRIPTION:We consider a model of a 2D superconductor with fixed order pa
 rameter amplitude and a critically disordered phase. We discuss analytical
  expressions for the spectral function (when the gap is much less than the
  Fermi energy) and obtain an exact result for the momentum space integral 
 over the Fermi surface.
