Finite-temperature simulations of the scissors mode in Bose-Einstein condensed gases.

摘要: The dynamics of a trapped Bose-condensed gas at finite temperatures is described by generalized Gross-Pitaevskii equation for the condensate order parameter and semiclassical kinetic thermal cloud, solved using N-body simulations. two components are coupled mean fields as well collisional processes that transfer atoms between two. We use this scheme to investigate scissors modes in anisotropic traps function temperature. Frequency shifts damping rates mode extracted, found be good agreement with recent experiments.
