Generalization of the Iterative Perturbation Theory and Metal–Insulator Transition in Multi-Orbital Hubbard Bands
/ Authors
/ Abstract
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 degener...
