Vagabonding electrons 4 2.2 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; Hhop which describes quantum mechanical hopping of electrons, and Hint which describes nonlinear repulsive interaction. Either Hhop or Hint alone is easy to Introduction to Hubbard model and exact diagonalization S Akbar Jafari Department of Physics, Isfahan University of Technology, Isfahan 84156-83111, Iran E-mail : sa.jafari@cc.iut.ac.ir The Hubbard model is an approximate model used, especially in solid-state physics, to describe the transition between conducting and insulating systems. The Hubbard model, named after John Hubbard, is a simple model of interacting particles in a lattice, with only two terms in the Hamiltonian (see example below): a kinetic term allowing for tunneling ("hopping") of particles between sites of 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 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. Introduction The Hubbard model has a relatively long history. Very early (in the 1950s) it was used by Pariser, Pople and Parr for orbital calculations and to describe molecules in quantum chemistry (PPP-method, see e.g.
