Research Abstract

Localization of electrons, which is a typical property of strongly correlated electrons systems, has been intensively studied in condensed matter physics. However, the complexity of the surroundings around electrons in condensed matters makes it difficult to understand the mechanism of the localization. In this project, we have made the surroundings around strongly correlated electrons simple, and have clarified the mechanism of localization in view of electronic structure.
