We generate independent configurations of the ideal gas. At finite $N$, the superfluid density changes by a certain correlation function in the limit $a \\to 0$; the $N \\to \\infty$ limit is taken afterwards. We argue that our result is independent of the order of limits. Detailed knowledge of the non-interacting system for finite $N$ allows us to avoid finite-size scaling assumptions.", "revisions": [ { "version": "v2", "updated": "1999-10-15T10:15:23.000Z" } ], "analyses": { "keywords": [ "weakly interacting bose gas", "transition temperature", "monte carlo calculation", "superfluid density changes", "generate independent configurations" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
