For the limit of weak tunnel coupling and in the regime of pumping frequencies up to the tunneling rates, $\\Omega \\lesssim \\Gamma/\\hbar$, we perform an exact resummation of contributions of all orders in the pumping frequency. As striking non-adiabatic signatures, we find frequency-dependent phase shifts in the charge and spin currents, which allow for an effective single-parameter pumping as well as pure spin without charge currents.", "revisions": [ { "version": "v2", "updated": "2009-10-09T08:07:49.000Z" } ], "analyses": { "subjects": [ "73.23.Hk", "72.10.Bg", "85.75.-d" ], "keywords": [ "interacting quantum dots", "non-adiabatic pumping", "study non-adiabatic two-parameter charge", "single-level quantum dot", "pumping frequency" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review Letters", "year": 2009, "month": "Sep", "volume": 103, "number": 13, "pages": 136801 }, "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2009PhRvL.103m6801C" } } }
