概要
- 論文の詳細を見る
The iterative perturbation theory of the dynamical mean field theory is generalized to arbitrary electron occupation for multi-orbital Hubbard bands. We present numerical results for doubly degenerate Eg bands on a simple cubic lattice. The spectrum shows the electron ionization and affinity levels of different electron occupations. For sufficiently large Coulomb interaction, a gap opens in the spectrum at an integer filling of electrons and the system becomes an insulator. The present scheme is easily combined with electronic structure theory in the local spin density approximation.
