We consider such a phase transition and show that the transition region in the vicinity of the critical point exhibits scalings that reflect a compromise between the rate at which the transition is imposed (i.e., the gradient of the control parameter) and the scaling of the divergent healing length in the critical region. Our results suggest a method for the direct measurement of the scaling exponent nu.", "revisions": [ { "version": "v2", "updated": "2009-04-29T16:42:58.000Z" } ], "analyses": { "keywords": [ "quantum phase transition", "bose-einstein condensate", "ferromagnetic", "transition region", "broken symmetry" ], "tags": [ "journal article" ], "publication": { "doi": "10.1088/1367-2630/11/6/063014", "journal": "New Journal of Physics", "year": 2009, "month": "Jun", "volume": 11, "number": 6, "pages": "063014" }, "note": { "typesetting": "TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2009NJPh...11f3014D" } } }
