Nonequilibrium dynamics of optical-lattice-loaded Bose-Einstein-condensate atoms: Beyond the Hartree-Fock-Bogoliubov approximation

The nonequilibrium dynamics of a Bose-Einstein condensate selectively loaded into every third site of a one-dimensional optical lattice was discussed. A two-particle irreducible (2PI) closed-time-path (CTP) effective action was used for the purpose. Three different approximations under the 2PI CTP s...
