We review the slave-boson representations of the Hubbard model. When both spin and charge fermion degrees of freedom are represented by Bose fields, the approach is equivalent at the “self-consistent” saddle point level to the Gutzwiller approximation (GA). 1.2 Model Hamiltonians In this section we want to motivate our description of the cuprate CuO 2 layer. First we want to show that such a 2D system can be described by an extended Hubbard model and then we argue that a single band Hubbard model is probably sufficient to capture the relevant physics. 2013-10-01 · We review the physics of the Bose–Hubbard model with disorder in the chemical potential focusing on recently published analytical arguments in combination with quantum Monte Carlo simulations. Apart from the superfluid and Mott insulator phases that can occur in this system without disorder, disorder allows for an additional phase, called the Bose glass phase.

There is a belief that they are actually interrelated and not mutually exclusive, although a convincing demonstration of any such connection is yet to be found. The choice of these topics as subjects of our review is dictated by our common interests. Understanding phase diagrams of simple model systems precisely is about far more than testing well-established theory, and the 2D Fermi-Hubbard model is perhaps the best illustration of this point. A few decades after it was introduced, the model took on a new significance in the search for the cause of high-temperature superconductivity in copper-oxide compounds.

Can the Hubbard model provide a sensible description of it? Because our model is two dimensional, we can only have magnetic long-range order in the ground state; at T ~0, a continu-ous symmetry cannot be broken in two dimensions.

It is impossible to solve the corresponding many-body problems analytically or numerically, although much insight can be gained from the analysis of simplified models. An important example is the Hubbard model, which describes interacting electrons in narrow energy bands, and which has been applied to problems as diverse as high-Tc superconductivity, band magnetism, and the metal-insulator transition.

The Hamiltonian of the Hubbard model consists of two parts: which describes quantum mechanical hopping of electrons, and which describes non-linear repulsive interaction. Here, we review some of the vast literature on this subject, with a focus on more recent non-standard forms of the Hubbard model. After giving an introduction to standard (fermionic and bosonic) Hubbard models, we discuss briefly common models for mixtures, as well as the so-called extended Bose-Hubbard models, that include interactions between Hubbard model is more involved than in other cases. We expect the reader who has mastered the solution of the Hubbard model to be able to apply his/her knowledge readily to other integrable theories. This volume does not pretend to cover its subject completely.
