Abstract

A complex nonlinear Schroedinger equation, coupled to the Boltzmann equation, was used to calculate the frequencies and damping rates of the low lying collective modes of a Bose-Einstein condensed gas. A time independent Gaussian trial function for the condensate wave function was used to solve the linear response of these equations. The calculations were characterized by two dimensionless parameters proportional to the condensate-noncondensate collision times.
