Dark-state polaritons (DSPs) are formed in the interaction of light with laser-driven 3-level Lambda-type atoms and are the basis of phenomena such as electromagnetically induced transparency (EIT), ultra-slow and stored light. They have long intrinsic lifetimes and in a stationary set-up with two counterpropagating control fields of equal intensity have a 3D quadratic dispersion profile with variable effective mass. Since DSPs are bosons they can undergo a Bose-Einstein condensation at a critical temperature which can be many orders of magnitude larger than that of atoms. We show that thermalization of polaritons can occur via elastic collisions mediated by a resonantly enhanced optical Kerr nonlinearity on a time scale short compared to the decay time. Finally condensation can be observed by turning stationary into propagating polaritons and monitoring the emitted light.", "revisions": [ { "version": "v1", "updated": "2008-07-22T13:57:16.000Z" } ], "analyses": { "subjects": [ "42.50.Gy", "03.75.Hh", "71.35.Lk" ], "keywords": [ "bose-einstein condensation", "stationary-light polaritons", "enhanced optical kerr nonlinearity", "3d quadratic dispersion", "time scale short" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review Letters", "year": 2008, "month": "Oct", "volume": 101, "number": 16, "pages": 163601 }, "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008PhRvL.101p3601F" } } }
