The depletion in Bose Einstein condensates using Quantum Field Theory in curved space

arXiv:cond-mat/0610367 · doi:10.1103/PhysRevA.75.043622

Abstract

Using methods developed in Quantum Field Theory in curved space we can estimate the effects of the inhomogeneities and of a non vanishing velocity on the depletion of a Bose Einstein condensate within the hydrodynamical approximation.
