We argue that in the limit of strong repulsion U t, the system with one electron per site is a Mott insulator with antiferromagnetic exchange J = 4t2/U. The details will be derived in a homework problem of a 2site Hubbard model. SOME INTRODUCTORY NOTES ON THE HUBBARD MODEL 5 electron not in a spherical s-shell, but in a p- or d-shell. Due to the anisotropy of these shells, it can even happen that next nearest hoping Hubbard model has become a laboratory for theoretical studies of non-perturba-tive effects in strongly correlated electron systems. Many of the tools available for the analysis of such systems have been applied to this model, both to pro-vide complementary insights to what is known from the exact solution or as an ultimate test of their quality. 3.5 The Hubbard Model: Tight-binding, Hopping, and Mott Insulators The following notes contain excerpts from, and paraphrasing of, Chapter 4 in “Lecture Notes on Electron Correlation and Magnetism” by Patrik Fazekas, World Scientific, Singapore, 1999.
