| Outline of Final Research Achievements |
In this project, we have theoretically studied correlation effects in topological quantum condensed phases, and explored emergent novel topological quantum phenomena. Our study has widely addressed correlated electron systems as well as cold atomic systems. Concerning solid state systems, we have performed precise calculations in one-dimensional correlated electron systems, and also dynamical mean field theory calculations in two-dimensional systems. We have thus clarified characteristic properties inherent in the topological Mott insulators and the associated edge Mott states. Concerning cold atomic systems, we have treated laser-induced topological phase transitions, and proposed a protocol for its realization. We have also elucidated topological properties of quasi-periodic interacting boson systems.
