At small interaction and small randomness, there is an infra-red stable fixed curve which merges with the strongly interacting infra-red unstable line at a critical endpoint, along which the dynamical critical exponent $z=1$.", "revisions": [ { "version": "v1", "updated": "2007-10-15T20:21:21.000Z" } ], "analyses": { "subjects": [ "73.61.Wp", "71.10.Pm", "71.10.Hf", "71.23.-k" ], "keywords": [ "2d coulomb interacting dirac fermions", "renormalization group approach", "random gauge potential", "interacting infra-red unstable line" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review B", "year": 2008, "month": "Jan", "volume": 77, "number": 3, "pages": "033410" }, "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008PhRvB..77c3410V" } } }
