Phys. Rev. A 70, 033604 (2004) [5 pages]Vortex lattices in the lowest Landau level for confined Bose-Einstein condensatesReceived 5 April 2004; revised 7 May 2004; published 17 September 2004 We present the results of numerical calculations of the ground states of weakly interacting Bose-Einstein condensates containing large numbers of vortices. Our calculations show that these ground states appear to be close to uniform triangular vortex lattices. However, slight deviations from a uniform triangular lattice have dramatic consequences on the overall particle distribution. In particular, we demonstrate that the overall particle distribution averaged on a length scale large compared to the vortex lattice constant is well approximated by a Thomas-Fermi profile. © 2004 The American Physical Society URL:
