Two very distinct time scales are found: one for the creation of the interference is of the order of the detection time for a few single atoms and another, for the preparation of coherent states, of the order of the detection time for a significant fraction of the total number of atoms. Approximate analytic solutions are derived and compared with exact numerical results.", "revisions": [ { "version": "v1", "updated": "1999-03-05T10:55:42.000Z" } ], "analyses": { "keywords": [ "bose-einstein condensates", "atom detection", "detection time", "coherent state", "distinct time scales" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 10, "language": "en", "license": "arXiv", "status": "editable", "inspire": 496315 } } }
