| Outline of Final Research Achievements |
We investigated the electronic states of low dimensional strongly correlated electron system, such as molecular conductors, inorganic oxides and graphene related materials, by using various theoretical methods. In addition, we explored the possibility for control of the various states by the external fields. For example, we succeeded in explaining the discrepancy between TTF[Co(Pc)CN2]2 and TTF[Fe(Pc)CN2]2 in the magnitude of resistivity and in the sign of magnetoresistance. In addition, we developed the improved renormalization group method and applyed it to high-Tc cuprate superconductors and Ruthenium oxides. We obtained many results which can explain the experimantal observations.
