Appendix C.4 on thermal weighting has been extended to include discussion [see Eqs.(C.22-24)] of average energy of electron trajectories", "journal": "International Journal of Modern Physics B, 22, 727-833 (2008)", "categories": [ "cond-mat.dis-nn", "cond-mat.mes-hall" ], "abstract": "We have rederived the controversial influence functional approach of Golubev and Zaikin (GZ) for interacting electrons in disordered metals in a way that allows us to show its equivalence, before disorder averaging, to diagrammatic Keldysh perturbation theory. By representing a certain Pauli factor (1-2 rho) occuring in GZ's effective action in the frequency domain (instead of the time domain, as GZ do), we also achieve a more accurate treatment of recoil effects. With this change, GZ's approach reproduces, in a remarkably simple way, the standard, generally accepted result for the decoherence rate. -- The main text and appendix A.1 to A.3 of the present paper have already been published previously; for convenience, they are included here again, together with five additional, lengthy appendices containing relevant technical details.", "revisions": [ { "version": "v2", "updated": "2008-04-10T10:55:55.000Z" } ], "analyses": { "keywords": [ "interacting electrons", "disordered conductors", "decoherence", "appendices containing relevant technical", "controversial influence functional approach" ], "tags": [ "journal article" ], "publication": { "doi": "10.1142/S0217979208039083", "journal": "International Journal of Modern Physics B", "year": 2008, "volume": 22, "number": 7, "pages": 727 }, "note": { "typesetting": "TeX", "pages": 106, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008IJMPB..22..727V" } } }
