After having presented our argument against the above attribution, we show that the known phenomenology, including a discrepancy of about one order of magnitude with the predictions of Bose- Einstein condensation, is in good agreement with the electromagnetic coherence induced on the alkali atoms by the long range electrodynamic interactions. We also predict that for temperatures lower than a well defined $T_{BEC}$, the state predicted by Bose and Einstein coexists with the new coherent electrodynamic state.", "revisions": [ { "version": "v1", "updated": "1998-12-01T18:51:32.000Z" } ], "analyses": { "keywords": [ "electrodynamic condensates", "bose-einstein", "long range electrodynamic interactions", "coherent electrodynamic state", "magnetically trapped ultracold alkali atoms" ], "note": { "typesetting": "TeX", "pages": 6, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "1998cond.mat.12018D" } } }
