Multiorbital Extended Hubbard Model


The multiorbital extended Hubbard model provides a natural method for incorporating many particle effects into electronic structure calculations. To date only the single orbital model has been extensively studied despite the fact that magnetic and superconducting materials including manganites and cuprates would seem to require more than one orbital. In this talk I review the model itself, the choice of parameters (it is a semiempirical model), and cite a few previous applications. This provides the background for the Quantum Monte Carlo calculations currently being performed by Isabel Campos and me.
