REVIEW ARTICLE: The Hubbard model - an introduction and selected rigorous results. 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.

Several different models have recently been proposed to explain high temperature superconductivity.

This is a review of two such proposals, namely the Hubbard and anyon models. There is a belief that they are actually interrelated and not mutually exclusive, although a convincing demonstration of any such connection is yet to be found.

Hubbard model review

2013-09-02 · Models are abundant in virtually all branches of physics, with some achieving iconic status. The Hubbard model, celebrating its golden jubilee this year, continues to be one of the most popular 2008-08-11 · Several simple but powerful models have been invented and successfully employed for the description of various condensed matter systems, including the Heisenberg spin and Hubbard models. Lately, the Hubbard model has been attracting renewed attention prompted by the remarkable experimental progress in cooling and trapping bosonic and fermionic atoms in optical lattices [ 2 ]. Review Article Out-of-Equilibrium Dynamics of the Bose-Hubbard Model MalcolmP.Kennett Department of Physics, Simon Fraser University, University Drive, Burnaby, BC, Canada VA S Correspondence should be addressed to Malcolm P. Kennett; malcolmk@sfu.ca Received November ; Accepted December Academic Editors: K. Kasamatsu and A. A. Kordyuk This is a review of two such proposals, namely the Hubbard and anyon models. There is a belief that they are actually interrelated and not mutually exclusive, although a convincing demonstration of any such connection is yet to be found. The choice of these topics as subjects of our review is dictated by our common interests. Understanding phase diagrams of simple model systems precisely is about far more than testing well-established theory, and the 2D Fermi-Hubbard model is perhaps the best illustration of this point.

Here we carry out a detailed analysis and 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.

In this contribution we introduce this model along with numerically exact method of diagonalization of the model. We use Quantum Monte Carlo simulations and exact diagonalization to explore the phase diagram of the Bose-Hubbard model with an additional superlattice potential. We first analyze the properties of superfluid and insulating phases present in the hard-core limit where an exact analytic treatment is possible via the Jordan-Wigner transformation.
