Effects of thermal phase fluctuations in a two-dimensional superconductor: an exact result for the spectral function.
Phys Rev Lett 105:2 (2010) 027002
Abstract:
We consider the single particle spectral function for a two-dimensional clean superconductor in a regime of strong critical thermal phase fluctuations. In the limit where the maximum of the superconducting gap is much smaller than the Fermi energy we obtain an exact expression for the spectral function integrated over the momentum component perpendicular to the Fermi surface.Low-temperature dynamical structure factor of the two-leg spin-1/2 Heisenberg ladder
