The transmission coefficient is equivalent to the conductance of a quantum dot connected to leads of quantum wires. We will show that the transmission coefficient is given by a sum over all discrete eigenstates without a background integral. An apparent \"background\" is in fact not a background but generated by tails of various resonance peaks. By using the expression, we will show that the Fano asymmetry of a resonance peak is caused by the interference between various discrete eigenstates. In particular, an unstable resonance can strongly skew the peak of a nearby resonance.", "revisions": [ { "version": "v1", "updated": "2010-10-07T05:59:05.000Z" } ], "analyses": { "keywords": [ "open quantum systems", "greens function", "resonant-state expansion", "transmission coefficient", "resonance peak" ], "tags": [ "journal article" ], "publication": { "journal": "International Journal of Theoretical Physics", "year": 2011, "month": "Apr", "volume": 50, "number": 4, "pages": 1105 }, "note": { "typesetting": "TeX", "pages": 7, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011IJTP...50.1105H" } } }
