We introduce a particular (circular) variant of the model, and show that the integer moments of the partition function in the high-temperature phase are given by the well-known Dyson Coulomb gas integrals. The CLD freezing scenario allows one to use those moments for extracting the distribution of the free energy in both high- and low-temperature phases. In particular, it yields the full distribution of the minimal value in the potential sequence. This provides an explicit new class of extreme-value statistics for strongly correlated variables, manifestly different from the standard Gumbel class. -", "revisions": [ { "version": "v2", "updated": "2008-08-18T14:20:45.000Z" } ], "analyses": { "keywords": [ "random energy model", "extreme value statistics", "logarithmically correlated potential", "well-known dyson coulomb gas integrals" ], "tags": [ "journal article" ], "publication": { "journal": "Journal of Physics A Mathematical General", "year": 2008, "month": "Sep", "volume": 41, "number": 37, "pages": 372001 }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008JPhA...41K2001F" } } }
