We show that a temperature gradient at a thermally-driven first-order transition gives rise to nontrivial universal scaling behaviors with respect to the length scale of the variation of the local temperature T(x). We propose a scaling ansatz to describe the crossover region at the surface where T(x)=Tc, where the typical discontinuities of a first-order transition are smoothed out. The predictions of this scaling theory are checked, and get strongly supported, by numerical results for the 2D Potts models, for a sufficiently large number of q-states to have first-order transitions. Comparing with analogous results at the 2D Ising transition, we note that the scaling behaviors induced by a smooth inhomogeneity appear quite similar in first-order and continuous transitions.", "revisions": [ { "version": "v2", "updated": "2014-06-30T12:09:36.000Z" } ], "analyses": { "subjects": [ "64.60.De", "05.70.Jk", "05.10.Cc", "05.70.Fh" ], "keywords": [ "first-order transition", "universal scaling effects", "temperature gradient", "smooth inhomogeneity appear quite similar", "nontrivial universal scaling behaviors" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review E", "doi": "10.1103/PhysRevE.89.062132", "year": 2014, "month": "Jun", "volume": 89, "number": 6, "pages": "062132" }, "note": { "typesetting": "TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1286765, "adsabs": "2014PhRvE..89f2132B" } } }
