## 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.

The Hamiltonian of the Hubbard model consists of two parts: which describes quantum mechanical hopping of electrons, and which describes non-linear repulsive interaction. I. INTRODUCTION John Hubbard, at the beginning of 1960, proposed in a series of articles a model to describe electrons in transi-tion metal monoxides and electron correlation in narrow energy bands. Due to the complexity of the study of these systems given the vast amount of bounds and continuum electron energy levels, Hubbard proposed to reduce the bard model in the half-filled-band case.

### 1 Introduction to the Hubbard model and its symmetries 1.1 The Hubbard Hamiltonian Most people at a graduate level of physics will be somewhat familiar with the one dimensional Hubbard model and it’s Hamiltonian. The model arises as a simpli ed version of the intractable Hamiltonian of a solid, that has to take into account all interactions. The Hubbard model describes a one dimensional

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.
