Microscopic Theory of Strongly Correlated Fermi Systems
Abstract We present here a new approach to a purely lattice (Hubbard) model for correlated Fermi systems. We first motivate the model, and describe its features in physical terms. We then show how a many body theory can be developed, illustrating it with the example of a very strongly correlated Hubbard model with a low density of holes, for which we show that a hole density expansion exists.
