| Outline of Final Research Achievements |
We employ the world-line quantum Monte-Carlo (QMC) method for quantum many body systems. The QMC method has been widely used since it obtained numerically unbiased exact solution of theoretical models including many body interactions. In addition to QMC method, we also employ other methods (e.g., the mean-field theory, the perturbation theory, the exact diagonalization method) to investigate topics under intense study such as multicomponent ultracold atomic gases, quantum spin liquids, chiral soliton lattice. As a result, we have obtained new insights on these topics.
