Acceleration of quasi-particle modes in Bose-Einstein condensates

arXiv:cond-mat/9807002 · doi:10.1016/S0375-9601(98)00680-X

Abstract

We analytically examine the dynamics of quasi-particle modes occuring in a Bose-Einstein condensate which is subject to a weak acceleration. It is shown that the momentum of a quasi-particle mode is squeezed rather than accelerated.
