The Energy of a Trapped Interacting Bose Gas
arXiv:cond-mat/9612216 · doi:10.1103/PhysRevA.56.2984
Abstract
A Bose gas in an external potential is studied by means of the semi-classical approximation. Analytical results are derived for the energy of an interacting Bose gas in a generic power-law trapping potential. An expression for the chemical potential below the critical temperature is also obtained. The theoretical results are in qualitative agreement with a recent energy measurement.
