into account all interactions. The Hubbard model describes a one dimensional chain of atoms of length Lwith periodic boundary conditions. The electrons have same-site and nearest-neighbor interactions only. The Hamiltonian of the model is given by a sum over hopping terms and same-site terms at every site. In second quantization it is given by [1] H= t XL j=1 X a=";# cy j;a c j+1;a+ c y j+1;a c j;a + U XL j=1 n

The Lanczos algorithm has been applied to the Hubbard model on a 4\\ifmmode\\times\\else\\texttimes\\fi{}4 square lattice and several equal-time correlation functions have been evaluated. This computation has been made possible by a classification of all the irreducible representations of the space symmetry group, which allowed a considerable reduction of the dimension of the Hilbert space of

II. much more complete technical review is in: “Strongly Correlated Materials: Insights From. 11 May 2010 The Fermi-Hubbard model is a key concept in condensed matter physics and provides crucial insights into electronic and magnetic properties in Chapter I we will review the basic ideas behind the physics of Mott insulators, stressing the underling concept of electron-electron correlation.

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. In this contribution we introduce this model along with numerically exact method of diagonalization of the model. We use Quantum Monte Carlo simulations and exact diagonalization to explore the phase diagram of the Bose-Hubbard model with an additional superlattice potential. We first analyze the properties of superfluid and insulating phases present in the hard-core limit where an exact analytic treatment is possible via the Jordan-Wigner transformation.

Kennett; malcolmk@sfu.ca Received November ; Accepted December Academic Editors: K. Kasamatsu and A. A. Kordyuk This is a review of two such proposals, namely the Hubbard and anyon models. 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.

PHYSICAL REVIEW B VOLUME 31,NUMBER 7 1 APRIL 1985 Two-dimensional Hubbard model: Numerical simulation study J.E.Hirsch Department ofPhysics, Uniuersity ofCalifornia, San Diego, La Jolia, California 92093 (Received 1 October 1984) We have studied the two-dimensional Hubbard model on a square lattice with nearest-neighbor hopping. 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. This is a review of two such proposals, namely the Hubbard and anyon models. 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 particles can either be fermions, as in Hubbard 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. Rather, we attempted to nd a balance between being didactic and being comprehensive.
