Abstract

The shift in condensation temperature caused by interactions is studied up to second order in the s-wave scattering length in a Bose-Einstein condensate trapped in a temperature-dependent three-dimensional generic potential. With no assumptions other than the mean-field approach and semiclassical approximations it is shown that the inclusion of a temperature-dependent trap improves the empirical values of the numerical parameters compared to those obtained in previous reports on the temperature shift.
