The model displays the full spectrum of the stochastic asymmetric XXZ chain plus new levels. We derive the Bethe equations and calculate the spectral gap for the totally asymmetric diffusion at half filling. While the standard asymmetric exclusion process without impurities belongs to the KPZ universality class with a exponent 3/2, our model has a scaling exponent 5/2.", "revisions": [ { "version": "v1", "updated": "2010-05-20T18:24:19.000Z" } ], "analyses": { "subjects": [ "02.50.Ey", "75.10.Pq", "02.30.Ik" ], "keywords": [ "asymmetric exclusion model", "impurities", "stochastic asymmetric xxz chain plus", "standard asymmetric exclusion process", "kpz universality class" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review E", "year": 2010, "month": "May", "volume": 81, "number": 5, "pages": "050104" }, "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010PhRvE..81e0104L" } } }
