The predicted cooling mechanism has its origins in magnetic field induced inelastic tunneling of the macroscopic superconducting phase associated with the junction. Furthermore, we show the voltage-drop over the junction is proportional to the average population of the vibrational modes in the stationary regime, a phenomena which can be used to probe the level of cooling.", "revisions": [ { "version": "v1", "updated": "2011-01-03T14:46:41.000Z" } ], "analyses": { "subjects": [ "85.85.+j", "73.23.-b", "74.50.+r", "85.25.Cp" ], "keywords": [ "inelastic macroscopic quantum tunneling", "current-biased josephson junction", "suspended nanowire", "ground-state cooling", "field induced inelastic tunneling" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review Letters", "year": 2011, "month": "Apr", "volume": 106, "number": 16, "pages": 167205 }, "note": { "typesetting": "TeX", "pages": 5, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011PhRvL.106p7205S" } } }
