Abstract
We consider a rotating Bose-Einstein condensate confined in combined harmonic\nand quartic traps, following recent experiments [V. Bretin, S. Stock, Y. Seurin\nand J. Dalibard, cond-mat/0307464]. We investigate numerically the behavior of\nthe wave function which solves the three-dimensional Gross Pitaevskii equation.\nWhen the harmonic part of the potential is dominant, as the angular velocities\n$Omega$ increases, the vortex lattice evolves into a giant vortex. We also\ninvestigate a case not covered by the experiments or the previous numerical\nworks: for strong quartic potentials, the giant vortex is obtained for lower\n$Omega$, before the lattice is formed. We analyze in detail the three\ndimensional structure of vortices.\n
