Abstract
We investigate the groundstates of weakly interacting bosons in a rotating trap as a function of the number of bosons, , and the average number of vortices, . We identify the filling fraction as the parameter controlling the nature of these states. We present results indicating that, as a function of , there is a zero temperature {\it 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.
