We compare the behavior of the Zero-Bias Anomaly against predictions from Kondo and spin polarization models. Both theories display shortcomings, the most dramatic of which are the linear electron-density dependence of the Zero-Bias Anomaly spin-splitting at fixed magnetic field B and the suppression of the Zeeman effect at pinch-off.", "revisions": [ { "version": "v1", "updated": "2008-10-06T13:12:23.000Z" } ], "analyses": { "subjects": [ "73.21.Hb", "72.10.Fk", "72.25.Dc", "73.23.Ad" ], "keywords": [ "zero-bias anomaly", "linear electron-density dependence", "average impurity separation", "theories display shortcomings", "spin polarization models" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review B", "year": 2009, "month": "Apr", "volume": 79, "number": 16, "pages": 161307 }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2009PhRvB..79p1307S" } } }
