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.

Jellium model assumes interacting electrons in a smeared potential of ions (no lattice structure considered) Hubbard model assumes a strong lattice potential and tightly bound electrons Hartree-Fock (HF) approximation introduces an effective one-particle problem by considering a single particle in a mean-field potential generated by all other Lecture at the 2010 TASI summer school on "String Theory and its Applications: from meV to the Plank Scale" held at the Theoretical Advanced Study Institute, In the slightly more than thirty years since its formulation, the Hubbard model has become a central component of modern many-body physics. It provides a paradigm for strongly correlated, interacting electronic systems and offers insights not only into the general underlying mathematical structure of many-body systems but also into the experimental behavior of many novel electronic materials. The fermionic Hubbard model on the two-dimensional hexagonal lattice at half-filling is the simplest model for undoped single layer graphene with screened interactions.

The Hubbard model, named after John Hubbard, is a simple model of interacting particles in a lattice, with only two terms in the Hamiltonian (see example below): a kinetic term allowing for tunneling ("hopping") of particles between sites of I will now show you how to solve for the quantum statistical mechanics of the simplest non-trivial Hubbard model, one with two connected sites. 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). 2019-09-12 Lecture 15: Information measures for continuous variables II and entropy maximization. Part IV: Machine Learning and statistics .

Left: The kinetic energy t.Right: The on-site repulsion U. A reasonable thought for the kinetic energy is an expression which destroys a fermion on one 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 Lecture 18: Hubbard model, screening and plasmons The Hubbard model is introduced. 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.
