Abstract

Spinor Bose Einstein Condensates are intriguing because of their vast range of different topological vortices. These states occur when a BEC gas is trapped in an optical lattice rather than in a magnetic well (which would result in scalar BEC vortices). A spinor BEC states also occur in a quantum gas when several hyperfine states of the atom co-exist in the same trap. A unitary quantum lattice algorithm that is ideally parallelized to all available processors is used to solve the evolution of non-eigenstate Skyrmions in a coupled BEC system. The incompressible kinetic energy spectrum of the inner quantum vortex ring core rapidly deviates from the k^-3 spectrum found in the evolution of scalar BECs.
