Condensation versus ordering: From the spherical models to Bose-Einstein condensation in the canonical and grand canonical ensemble
In this paper, we take a fresh look at the long-standing issue of the nature of macroscopic density fluctuations in the grand canonical treatment of the Bose-Einstein condensation (BEC). Exploiting the close analogy between the spherical and mean-spherical models of magnetism with the canonical and...
