"The BEC transition temperature of dilute gases: a not-so-simple problem in statistical mechanics"
ABSTRACT:
The phase transition temperature for Bose-Einstein condensation of a three-dimensional ideal gas of bosons at fixed density is something that every physicist learns to calculate in graduate school, if not before. Amusingly, the first correction to that result, from arbitrarily weak interactions, is sufficiently challenging that only now is there beginning to appear some theoretical agreement on its magnitude, roughly 80 years after Einstein computed the ideal gas result.
