Dissipative dynamics of a harmonically confined Bose-Einstein condensate

We study the dissipation of the center of mass oscillation of a harmonically confined condensate in the presence of a disorder potential. An extension of the harmonic potential theorem allows one to formulate the dynamics from the point of view of an oscillating disorder potential. This formulation...

Description
Summary:We study the dissipation of the center of mass oscillation of a harmonically confined condensate in the presence of a disorder potential. An extension of the harmonic potential theorem allows one to formulate the dynamics from the point of view of an oscillating disorder potential. This formulation leads to a rigorous result for the damping rate in the limit of weak disorder.
