Influence of Thermal Order Parameter Fluctuations on the Spectral Function of 2D Superconductors - Prof. Alexei Tsvelik, Brookhaven National Laboratory, USA
2010-02-26 14:15 - 15:15 UTC | TCM Seminar Room, Cavendish Laboratory
We consider a model of a 2D superconductor with fixed order parameter 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.
