Tc for dilute Bose gases: beyond leading order in 1/N / Peter Arnold, Boris Tomášik. -- Baym, Blaizot, and Zinn-Justin have recently used the large-N approximation to calculate the effect of interactions on the transition temperature of dilute Bose gases. We extend their calculation to next-to-leading order in 1/N and find a relatively small correction of26% to the leading order result. This suggests that the large-N approximation works surprisingly well in this application.
