Description

In this paper, the effect of fluctuations in the nonzero frequency modes of a weakly interacting Bose gas on the condensation temperature was studied in detail. The simple algorithm used to perturbatively calculate the effect in a high-temperature expansion in conjunction with zeta function regularization of infrared divergences was demonstrated to be reliable by showing that a host of known results are recovered
