Phys. Rev. A 66, 043619 (2002) [5 pages]Critical numbers of attractive Bose-Einstein condensed atoms in asymmetric trapsReceived 12 June 2002; published 30 October 2002 The recent Bose-Einstein condensation of ultracold atoms with attractive interactions led us to consider the possibility of probing the stability of its ground state in arbitrary three-dimensional harmonic traps. We performed a quantitative analysis of the critical number of atoms through a full numerical solution of the mean-field Gross-Pitaevskii equation. Characteristic limits are obtained for reductions from three to two and one dimensions, in perfect cylindrical symmetries as well as in deformed ones. © 2002 The American Physical Society URL:
