Non-classical critical exponents at Bose-Einstein condensation

I. Reyes-Ayala, F. J. Poveda-Cuevas, V. Romero-Rochin

We show that ideal Bose-Einstein condensation (BEC) in $d=3$ dimensions is a non-classical critical second order phase transition with exponents $\alpha =-1$, $\beta =1$, $\gamma =1$, $\delta =2$,…
