Here we report on a cavity opto-mechanical system in which a collective density excitation of a Bose-Einstein condensate is shown to serve as the mechanical oscillator coupled to the cavity field. We observe that a few photons inside the ultrahigh-finesse cavity trigger a strongly driven back-action dynamics, in quantitative agreement with a cavity opto-mechanical model. With this experiment we approach the strong coupling regime of cavity opto-mechanics, where a single excitation of the mechanical oscillator significantly influences the cavity field. The work opens up new directions to investigate mechanical oscillators in the quantum regime and quantum gases with non-local coupling.", "revisions": [ { "version": "v1", "updated": "2008-07-15T11:37:58.000Z" } ], "analyses": { "keywords": [ "bose-einstein condensate", "cavity field", "cavity opto-mechanics studies", "strongly driven back-action dynamics", "ultrahigh-finesse cavity trigger" ], "tags": [ "journal article", "famous paper" ], "publication": { "journal": "Science", "year": 2008, "month": "Oct", "volume": 322, "number": 5899, "pages": 235 }, "note": { "typesetting": "TeX", "pages": 6, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008Sci...322..235B" } } }
