Introduction to the Hubbard Model 6.3 2 Some notation and review of Green functions We ﬁrst introduce some notation that will be used frequently and give a brief review of imag-inary time Green functions. There are numerous excellent textbooks on the use of ﬁeld theory for condensed matter physics where more details can be found [5–7].

I. INTRODUCTION The Hubbard model' is defined by the lattice Hamil-tonian: I=gt,,(c; c, +H.c.)+U+n;,n;, pg(n;, —+n;,). It describes a single s band in a tight-binding basis, with a local electron-electron repulsion U for electrons of oppo-site spin at the same atomic orbital. The model is thought The Hubbard model is essentially a one parameter model in the ratio U/|t| where t is an average t ij, since the magnitude of t just sets the energy scale, and is the simplest many body Hamiltonian to include electron correlation explicitly. Elementary Introduction to the Hubbard Model 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.

Elementary Introduction to the Hubbard Model I. INTRODUCTION The Hubbard model offers one of the most simple ways to get insight into how the interac-tions between electrons can give rise to insulating, magnetic, and even novel superconducting effects in a solid. It was written down in the early 1960’s and initially applied to understand-ing the behavior of the transition metal monoxides
