| Outline of Final Research Achievements |
We theoretically investigated the physics of frustrated many-body systems including quantum antiferromagnets and cold atomic gases in an optical lattice. Using the numerical cluster mean-field plus scaling method, we succeeded in a quantitative, microscopic analysis that can be directly compared with experimental measurements for frustrated antiferromagnets. Furthermore, motivated by the recent realization of synthetic spin-orbit coupling in cold-atom systems, we explored new theoretical models that can be created by the latest techniques, and especially, revealed a rich variety of ground-state properties of spin-orbit-coupled Bose gases in a two-dimensional optical lattice.
