Abstract
We show that ideal Bose-Einstein condensation (BEC) in dimensions is a non-classical critical second order phase transition with exponents , , , , and , obeying all the scaling equalities. These results are found with no approximations or assumptions. The previous exponents are a critical universality class on its own, different from the so-far accepted notion that BEC belongs to the Spherical Model universality class.
