Using the exact solution of the Dorokhov-Mello-Pereyra-Kumar (DMPK) equation for transmission eigenvalues, we obtain the average and second moment of the conductance in the long-wire regime. For comparison, we employ the three-edge Chalker-Coddington model as the simplest example of channel-number-imbalanced systems with $m = 1$, and obtain the average and second moment of the conductance by using a supersymmetry approach. We show that the result for the Chalker-Coddington model is identical to that obtained from the DMPK equation.", "revisions": [ { "version": "v1", "updated": "2007-12-25T05:15:38.000Z" } ], "analyses": { "keywords": [ "perfectly conducting channels", "disordered wires", "asymptotic behavior", "conductance", "second moment" ], "tags": [ "journal article" ], "publication": { "doi": "10.1143/JPSJ.77.014703", "journal": "Journal of the Physical Society of Japan", "year": 2008, "month": "Jan", "volume": 77, "number": 1, "pages": 14703 }, "note": { "typesetting": "TeX", "pages": 20, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008JPSJ...77a4703T" } } }
