Phys. Rev. Lett. 87, 120405 (2001) [4 pages]Quantum Phases of Vortices in Rotating Bose-Einstein CondensatesReceived 5 April 2001; published 30 August 2001 We investigate the ground states of weakly interacting bosons in a rotating trap as a function of the number of bosons, N, and the average number of vortices, NV. We identify the filling fraction ν≡N/NV as the parameter controlling the nature of these states. We present results indicating that, as a function of ν, there is a zero temperature phase transition between a triangular vortex lattice phase, and strongly correlated vortex liquid phases. The vortex liquid phases appear to be the Read-Rezayi parafermion states. © 2001 The American Physical Society URL:
