Finite Temperature Perturbation Theory for a Spatially Inhomogeneous Bose-condensed Gas

P. O. Fedichev, G. V. Shlyapnikov

We develop a finite temperature perturbation theory (beyond the mean field) for a Bose-condensed gas and calculate temperature-dependent damping rates and energy shifts for Bogolyu…
