Research Abstract

For the strongly correlated electron systems, we constructed more accurate effective models and investigated physical properties quantitatively. In particular, we focus on the rare earth materials which are well known as the typical strongly correlated systems. Some physical quantities were calculated based on the constructed effective models. The obtained results were in good agreement with the experimental ones. We could propose the quantitative theoretical method to study the strongly correlated electron systems.
