The phase diagram is discussed in terms of a matrix-like order parameter, representing a symmetric phase (Mott insulator) and a symmetry-broken phase (Bose-Einstein condensate). An exact solution was found by introducing $N$ colors and taking the limit $N\\to\\infty$.", "revisions": [ { "version": "v1", "updated": "2003-03-27T20:42:40.000Z" } ], "analyses": { "keywords": [ "optical lattice", "bose gas", "study phase transitions", "phase diagram", "exact solution" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 12, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2003cond.mat..3593Z" } } }
