When slowly driven at zero temperature it can display an out-of-equilibrium phase transition associated with critical scaling (``crackling noise''), while it undergoes at equilibrium, under either temperature or disorder-strength changes, a thermodynamic phase transition. We show that the out-of-equilibrium and equilibrium critical behaviors are in the same universality class: they are controlled, in the renormalization-group (RG) sense, by the same zero-temperature fixed point. We do so by combining a field-theoretical formalism that accounts for the multiple metastable states and the exact (functional) RG. As a spin-off, we also demonstrate that critical fluids in disordered porous media are in the same universality class as the RFIM, thereby unifying a broad spectrum of equilibrium and out-of-equilibrium phenomena.", "revisions": [ { "version": "v1", "updated": "2013-11-06T09:23:07.000Z" } ], "analyses": { "subjects": [ "11.10.Hi", "75.40.Cx" ], "keywords": [ "universality class", "quenched random field", "thermodynamic phase transition", "out-of-equilibrium phase transition", "multiple metastable states" ], "tags": [ "journal article" ], "publication": { "doi": "10.1103/PhysRevB.89.104201", "journal": "Physical Review B", "year": 2014, "month": "Mar", "volume": 89, "number": 10, "pages": 104201 }, "note": { "typesetting": "TeX", "pages": 10, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1263822, "adsabs": "2014PhRvB..89j4201B" } } }
