"Forty Years of the Hubbard Model: From Transition Metal Oxides to Optical Lattices"

The Hubbard Hamiltonian is one of the most studied and most powerful models in condensed matter physics. It has been used to explain physics ranging from magnetism and insulating behavior in transition metal oxides, to superconductivity and density inhomogeneities in high termperature superconductors. Recently, the Hubbard Hamiltonian has seen a new and very interesting application to phase transition in ultracold, optically trapped atoms. In this talk, I will review the basic physics of the model and of some of our Quantum Monte Carlo studies, both within the context of solids and optical lattices.
