The Hubbard model is a `highly oversimplified model' for electrons in a solid which interact with each other through extremely short-ranged repulsive (Coulomb) interaction. The Hamiltonian of the Hubbard model consists of two parts: which describes quantum mechanical hopping of electrons, and which describes non-linear repulsive interaction.

The Hubbard model is essentially a one parameter model in the ratio U/|t| where t is an average t ij, since the magnitude of t just sets the energy scale, and is the simplest many body Hamiltonian to include electron correlation explicitly. Elementary Introduction to the Hubbard Model
In these notes we review some of the basic features of the 2D Hubbard model, thought of as the appropriate model for the description of the Cu — O planes in the cuprate superconductors. We discuss breifly the weakcoupling regime of the model and, in the opposite limit, the mapping of the one band Hubbard model onto an AFM Heisenberg model at half filling and onto the t — J model below half
