Virtual optical excitation from the 3A_2 ground state into the 3E excited state allows for spin rotations by virtue of the spin-spin interaction in the two-fold orbitally degenerate excited state. We derive an effective Hamiltonian for optically induced spin-flip transitions within the ground state spin triplet due to off-resonant optical pumping. Furthermore, we investigate the spin qubit formed by the Zeeman sub-levels with spin projection m_S = 0 and m_S = -1 along the NV axis around the ground state level anticrossing with regard to full optical control of the electron spin.", "revisions": [ { "version": "v1", "updated": "2012-06-15T16:08:28.000Z" } ], "analyses": { "subjects": [ "76.30.Mi", "03.67.-a", "31.15.xh", "71.70.Ej" ], "keywords": [ "spin state", "all-optical control", "ground state spin triplet", "two-fold orbitally degenerate excited state", "ground state level" ], "tags": [ "journal article" ], "publication": { "doi": "10.1103/PhysRevB.86.125204", "journal": "Physical Review B", "year": 2012, "month": "Sep", "volume": 86, "number": 12, "pages": 125204 }, "note": { "typesetting": "TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2012PhRvB..86l5204H" } } }
