| Outline of Final Research Achievements |
We established a theory that treats magnetism and superconductivity on equal footing. Starting from the dynamical mean-field theory, which has been widely applied to investigation of magnetism, spatial correlations are incorporated to address superconductivity. Applying the theory to the fundamental model for heavy-fermion systems, we revealed that there emerges a peculiar superconducting state that has not been expected in ordinary theories for superconductivity. This result affords a new insights into superconductivity that an exotic pairing could be induced by local-correlation effect.
In the latter of the period, we developed a new data-science approach to quantum many-body calculations. This approach is expected to play an crucial role in future applications of the "unified theory for magnetism and superconductivity" to realistic models for strongly correlated electron materials.
