In this contribution we introduce this model along with numerically exact method of diagonalization of the model. The Hubbard Model: Introduction and Selected Rigorous Results - NASA/ADS 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.

Even 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 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 pieces; H_hop which describes quantum mechanical hopping of electrons, and Hint which describes nonlinear repulsive interaction. Either H_hop or H_int alone is easy to For a good introduction to the Hubbard model and to correlated systems in general, see the book by P. Fazekas [5].

In these elements, the radial wave function of the 3d-electrons has a very small spatial extent. Therefore, when the 3dshell is occupied by several electrons, these are forced to be close to one 1 Introduction The Hubbard Hamiltonian (HH) offers one of the most simple ways to get insight into how the interactions between electrons give rise to insulating, magnetic, and even novel superconduct-ing effects in a solid. It was written down [1–4] in the early 1960’s and initially applied to Here we introduce the Hubbard model, without assuming advanced knowledge on the theoretical treatment of quantum many-particles systems. In Sect. 9.2 , we start from the wave function description of multiple electrons, and introduce the Fock space representation (also known as the “second quantization” formalism), which is standard in modern condensed matter physics.
