in the 2-dimensional Hubbard model. However, the lightly doped Mott-insulator – which most probably is the system to be understood in order to solve the many puzzles posed by the cuprate superconductors – is still far from being solved. Accordingly, the purpose of this lecture is to present some of the basic approximations developed for

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.When U is equal to zero it reduces exactly to the Hückel 2012-5-11 · Bose-Hubbard Model Stanimir Kondov May 5, 2008 Abstract The Bose-Hubbard hamiltonian will be introduced and justified as an effective description of some relevant physical systems (dilute alkali gases in optical lattices, arrays of Josephson junctions). I will also show a mean field theory solution and the resulting phase diagram. The Hubbard model describes a Mott transition with a mere minimum of tunable par- eters, and various exact statements and even exact solutions exist in certain limiting cases.
