We show that the problem of N radial SLEs in the unit disc is equivalent to Dyson's Brownian motion on the boundary of the disc, with parameter beta=4/kappa. As a result various equilibrium critical models give realisations of circular ensembles with beta different from the classical values of 1,2 and 4 which correspond to symmetry classes of random U(N) matrices. Some of the bulk critical exponents are related to the spectrum of the associated Calogero-Sutherland hamiltonian. The main result is also checked against the predictions of conformal field theory.", "revisions": [ { "version": "v4", "updated": "2003-11-11T15:19:51.000Z" } ], "analyses": { "keywords": [ "stochastic loewner evolution", "dysons circular ensembles", "conformal field theory", "dysons brownian motion", "continuum limit" ], "tags": [ "journal article" ], "publication": { "journal": "Journal of Physics A Mathematical General", "year": 2003, "month": "Dec", "volume": 36, "number": 49, "pages": 12343 }, "note": { "typesetting": "TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2003JPhA...3612343C" } } }
