By analogy with the method used for description of Vavilov-Cherenkov phenomenon, we have found a friction work created by the particle generated condensate polarization. For comparison we have found radiation intensity of excitations. Both methods gives the same result.", "revisions": [ { "version": "v1", "updated": "2001-09-13T11:19:59.000Z" } ], "analyses": { "keywords": [ "bose-condensed gas", "cherenkov radiation", "particle generated condensate polarization", "sound emission arises", "supersonic particle motion" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
