| Outline of Final Research Achievements |
We study theoretically nonequilibrium dynamics of cold atomic gases in artificial magnetic field, refereed to as synthetic gauge field in a view from weakly- to strongly-interacting regime. We study the vortex dynamics in spin-orbit coupled two-component Bose-Einstein condensates, clarifying the nontrivial dynamical behavior depending on the condensed phase for different strength of the spin-orbit coupling. We also study the atomic quantum simulations of lattice gauge theory, especially gauge-Higgs model, in one-, two-, and three dimensional optical lattice. We discuss the implementation, phase structure, and observable non equilibrium dynamics thoroughly, paying much attention to the experimental observation.
