We have then applied the formalism to graphene, for which we show that a non-linear effect of a circularly polarized light can open a gap in the Dirac cone, which leads to a photo-induced dc Hall current. This is numerically confirmed for a graphene ribbon attached to electrodes with the Keldysh Green's function.", "revisions": [ { "version": "v3", "updated": "2009-03-06T02:11:00.000Z" } ], "analyses": { "subjects": [ "73.43.-f", "72.40.+w", "78.67.-n", "85.60.-q" ], "keywords": [ "photovoltaic hall effect", "ac electric fields", "keldysh greens function", "photo-induced dc hall current", "dc source-drain fields" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review B", "year": 2009, "month": "Feb", "volume": 79, "number": 8, "pages": "081406" }, "note": { "typesetting": "TeX", "pages": 5, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2009PhRvB..79h1406O" } } }
