Abstract

Vortex configurations in rotating Bose-Einstein condensed gases trapped in power-law potentials are studied. Energy considerations reveal that when the confining potential is stronger than harmonic, vortices with quantum numbers larger than one are energetically favorable if the interaction is weak enough. For a quartic potential, criteria are established for the existence of two-, three-, and fourfold quantized vortices.
