Collisional matter-phase damping in Bose-condensed gas
arXiv:cond-mat/9612086
Abstract
Collisional damping of the excitations in a Bose-condensed gas is investigated over the wide range of energies and temperatures. Numerical results for the damping rate are presented and a number of asymptotic and interpolating expressions for it are derived.
