In simulations in a restricted ensemble without defects, the system appears to remain ordered at all temperatures. Suppression of topological defects on the square plaquettes in the modified XY- model leads to complete elimination of the phase transition observed in this model.", "revisions": [ { "version": "v3", "updated": "2010-03-26T15:17:56.000Z" } ], "analyses": { "subjects": [ "64.60.an", "05.10.Ln", "03.75.Lm" ], "keywords": [ "monte carlo study", "phase transition", "modified xy model", "topological defects", "monte carlo simulation" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review E", "year": 2010, "month": "Apr", "volume": 81, "number": 4, "pages": "041120" }, "note": { "typesetting": "TeX", "pages": 19, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010PhRvE..81d1120S" } } }
