Construction of effective model with realistic electronic structures of Strongly correlated electron systems and its analysis

对于强相关电子系统，我们建立了更精确的有效模型，并对其物理性质进行了定量研究。我们特别关注了稀土材料，这是众所周知的典型的强相关体系。根据所建立的有效模型计算了一些物理量。所得结果与实验结果吻合较好。我们可以提出定量的理论方法来研究强相关电子系统。

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.
