Validity of the Hohenberg Theorem for a Generalized Bose-Einstein Condensation in Two Dimensions
W. J. Mullin, M. Holzmann, F. Laloe
Several authors have considered the possibility of a generalized Bose-Einstein condensation (BEC) in which a band of low states is occupied so that the total occupation number is m…
