Abstract
We calculate the dynamics of local and non-local correlation functions of a three dimensional weakly interacting Bose gas after an interaction quench. Within the Bogoliubov approximation we discuss the resulting quasi-steady prethermal state and relaxation to it. We finally discuss the decay rates of Bogoliubov quasi-particles characterizing the expected departure from the prethermal state towards a fully thermalized one.
