We provide numerical evidence that bound states give rise to persistent, non-decaying current oscillations in the junction. We also show that the amplitude of these oscillations can exhibit a strong dependence on the history of the applied potential as well as on the initial equilibrium configuration. Our simulations allow for a quantitative investigation of several transient features. We also discuss the existence of different time-scales and address their microscopic origin.", "revisions": [ { "version": "v1", "updated": "2008-02-18T17:02:28.000Z" } ], "analyses": { "subjects": [ "05.60.Gg", "72.10.-d", "73.23.-b", "73.63.-b" ], "keywords": [ "time-dependent quantum transport", "bound states", "initial equilibrium configuration", "charge transport", "transient features" ], "tags": [ "journal article" ], "publication": { "journal": "Applied Physics A: Materials Science & Processing", "year": 2008, "month": "Nov", "volume": 93, "number": 2, "pages": 355 }, "note": { "typesetting": "TeX", "pages": 10, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008ApPhA..93..355K" } } }
