However, according to recent time-resolved measurements of P emission originating from inelastic exciton-exciton scattering, it looks rather natural to consider that the exciton-polariton is created in a finite time scale which is restricted by a coherence volume of the exciton after the scattering. In this interpretation, the exciton remains in this time scale far below its resonance energy as a transient state in a series of processes without violating the quantum physics.", "revisions": [ { "version": "v1", "updated": "2014-11-13T02:54:04.000Z" } ], "analyses": { "subjects": [ "78.20.Bh", "78.47.jd", "78.45.+h", "78.55.-m" ], "keywords": [ "resonance frequency", "inelastic scattering", "resonance energy", "finite time scale" ], "publication": { "doi": "10.1103/PhysRevB.91.235205", "journal": "Physical Review B", "year": 2015, "month": "Jun", "volume": 91, "number": 23, "pages": 235205 }, "note": { "typesetting": "TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2015PhRvB..91w5205B" } } }
