| Research Abstract |
We studied the electronic structure of metal/insulator interfaces by quantum mechanical calculations. In particular, to describe the Mott insulator arising from strong Coulomb interactions, we derived a method to apply dynamical mean-field theory to multilayer systems such as semi-infinite interfaces. By applying this method and also by incorporating interatomic correlation effects, we clarified how metallic states penetrate into the insulator layers at the metal/Mott insulator interface.
