By the way, the quantum mechanics of the two-site Hubbard model is useful for understanding the binding of molecules like H 2 (take a look at Feynman’s Lectures on Physics, vol. III, chapter 10). simplest theories of Mott insulators is the Hubbard model (1963). When t U z /(2 ) , Egap 0, leading to the conduction as a result of spontaneous generation of Ni3+ and Ni+. We call an insulator with large U as Mott insulator.

The Bose-Hubbard model is used to study bosons in optical lattices. In this thesis we will use an extended Bose-Hubbard model to study a type of completely 

Therefore, when the 3dshell is occupied by several electrons, these are forced to … The Hubbard model presents one of the simplest ways to obtain an understanding of the mechanisms through which interactions between electrons in a solid can give rise to insulating versus conducting, magnetic, and even novel superconducting behaviour. 1995-12-26 The Hubbard model can thus be viewed as the simplest possible model of correlated fermions. The Hubbard model contains few independent parameters. If we assume that hopping is only allowed between nearest-neighbor lattice sites, and if we assume translational invariance, the hopping is described by a single parameter.
