T_{c} for dilute Bose gases: Beyond leading order in 1/N
Abstract
Baym, Blaizot, and ZinnJustin have recently used the largeN approximation to calculate the effect of interactions on the transition temperature of dilute Bose gases. We extend their calculation to nexttoleading order in 1/N and find a relatively small correction of 26% to the leading order result. This suggests that the largeN approximation works surprisingly well in this application.
