Phenomenological damping in trapped atomic Bose-Einstein condensates

Quantum Physics 2009-10-31 v1

Abstract

The method of phenomenological damping developed by Pitaevskii for superfluidity near the λ\lambda point is simulated numerically for the case of a dilute, alkali, inhomogeneous Bose-condensed gas near absolute zero. We study several features of this method in describing the damping of excitations in a Bose-Einstein condensate. In addition, we show that the method may be employed to obtain numerically accurate ground states for a variety of trap potentials.
