Based on the validity of the cluster expansion for the canonical partition function in the high temperature - low density regime we prove moderate and precise large deviations from the mean value of the number of particles with respect to the grand-canonical Gibbs measure. In this way we have a direct method of computing both the exponential rate as well as the pre-factor and obtain explicit error terms. Estimates comparing with the infinite volume versions of the above are also provided.", "revisions": [ { "version": "v1", "updated": "2020-01-16T14:47:16.000Z" } ], "analyses": { "subjects": [ "60F05", "60F10", "82B05" ], "keywords": [ "precise large deviations", "cluster expansion", "local moderate", "low density regime", "regular pair potential" ], "note": { "typesetting": "TeX", "pages": 30, "language": "en", "license": "arXiv", "status": "editable" } } }
