Elgaroy" ], "comment": "4 pages, 2 figures", "categories": [ "cond-mat.stat-mech" ], "abstract": "We calculate the characteristic length scale of a vortex line in a dilute, superfluid gas of fermionic atoms, and find that it is in general smaller, and has a weaker density dependence than the BCS coherence length. Taking this into account, we find the energy of a vortex line to be larger than has previously been estimated. As a consequence, the critical frequency for formation of vortices in trapped fermion gases can be significantly larger than earlier calculations have suggested.", "revisions": [ { "version": "v1", "updated": "2001-11-22T19:45:17.000Z" } ], "analyses": { "keywords": [ "characteristic length scale", "vortex line", "superfluid fermi gas", "weaker density dependence", "bcs coherence length" ], "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2001cond.mat.11440E" } } }
