Single-Particle Excitations in a Two-Dimensional Strong-Coupling Superconductor
D. W. Hess, J. J. Deisz, J. W. Serene
We present calculations of the single-particle excitation spectrum for a 2D strong-coupling superconductor in a conserving approximation. Spectral weight at low frequency is substa…

Improved Treatment of Frequency Sums in Propagator-Renormalized Perturbation Theories
J. J. Deisz, D. W. Hess, J. W. Serene
We present a massively parallel algorithm for calculating the self-energy in self-consistent finite temperature perturbation theory for lattice models. The algorithm uses analytic…
