Unusual States of Vortex Matter in Mixtures of Bose-Einstein Condensates on Rotating Optical Lattices
Superfluid parameter space vortex lattice parameters the mixture of condensed matter optical lattice

Abstract: We study a superfluid in a rotating anharmonic trap and explicate a rigorous proof of a transition from a vortex lattice to a giant vortex state as the rotation is increased beyond a limitin...
