Abstract

A study of the mechanical excitation spectrum of Bose-Einstein condensates (BEC) and the use of excitation spectroscopy as a sensitive technique for detecting the presence of spectroscopy are presented. Hartree-Fock-Bogoliubov (HFB) formulation of mean field theory is applied to calculate the properties of finite BEC in anisotropic atom traps. This theory includes the particle pair density and provide better estimates of the condensate fraction at finite temperature. Comparisons of Popov and full HFB results with the experimental data is also presented.
