In both cases the ground state is unique. The The Hubbard Model The Hubbard model is the simplest many-body Hamiltonian which allows a meaningful description of two opposing tendencies: ! The kinetic energy (electron hopping) acts to delocalize the electrons into itinerant states (Bloch states), leading to metallic behavior. Hubbard model is an important model in theory of strongly correlated electron systems.

This volume does not pretend to cover its subject completely. Rather, we attempted to nd a balance between being didactic and being comprehensive. 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.
Lafayette Ronald Hubbard, mer känd som L. Ron Hubbard, född 13 mars 1911 i Tilden, Nebraska, död 24 januari 1986 i Creston, San Luis Obispo County, Kalifornien, var en amerikansk författare av magasinsnoveller inom äventyr, western och science fiction – så kallad pulp fiction.
REVIEW ARTICLE: The Hubbard model - an introduction and selected rigorous results. The Hubbard model is a `highly oversimplified model' for electrons in a solid which interact with each other through extremely short-ranged repulsive (Coulomb) 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 neighboring sites, next-neighbor sites, and so on. The Hubbard model was proposed in the 1960s to describe electrons in 3dtransition metals. In these elements, the radial wave function of the 3d-electrons has a very small spatial extent. Therefore, when the 3dshell is occupied by several electrons, these are forced to be close to one 1995-12-26 · Abstract: The Hubbard model is a "highly oversimplified model" for electrons in a solid which interact with each other through extremely short ranged repulsive (Coulomb) interaction.

It constitutes the simplest model system that describes the competition between the kinetic energy and interactions of electrons in the lattice potential of an ionic crystal [2].

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. We find that the model does exhibit long-range antiferromag-netic order in the ground state for the half-filled-band
The Fermi-Hubbard model is a key concept in condensed matter physics and provides crucial insights into electronic and magnetic properties of materials. Yet, the intricate nature of Fermi systems poses a barrier to answering important questions concerning d-wave superconductivity and quantum magnetism. Recently, it has become possible to experimentally realize the Fermi-Hubbard model using a Originally, the Hubbard model has been developed in theoretical condensed matter physics [1]. It constitutes the simplest model system that describes the competition between the kinetic energy and interactions of electrons in the lattice potential of an ionic crystal [2].
