We introduce a family of zero dimensional models for which we can calculate the exact value of the critical exponents $\\beta_m$ for all the moments. The results are obtained through asymptotic expansions that use the distance to onset as a small parameter. The examined family displays a variety of behaviors of the critical exponents that includes anomalous exponents: exponents that differ from the deterministic (mean-field) prediction, and multiscaling: non-linear dependence of the exponents on the order of the moment.", "revisions": [ { "version": "v1", "updated": "2012-07-18T12:12:38.000Z" } ], "analyses": { "keywords": [ "critical exponents", "zero dimensions", "zero dimensional models", "asymptotic expansions", "exact value" ], "tags": [ "journal article" ], "publication": { "doi": "10.1007/s10955-012-0615-6", "journal": "Journal of Statistical Physics", "year": 2012, "month": "Nov", "volume": 149, "number": 4, "pages": 738 }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2012JSP...149..738A" } } }
