Outline of Final Research Achievements

Mixtures of Bose-Fermi atoms on optical lattices were studied by taking account of the influences from confinement potential, random potential, pseudo-periodic potential, artificial magnetic field, and artificial spin-orbit interactions in order to comprehensively understand characteristic behaviors in both analytical and numerical approaches. In the study, a local Mott state of the mixtures in the confinement potential and its internal structure were clarified. Also the role of Bose-Fermi interactions on the localization phenomena of the mixtures in random or pseudo-periodic potentials was unveiled. It was also found how an artificially-created magnetic field and spin-orbit interactions affect the behavior of the mixtures.
