Interpolation between Hubbard and supersymmetrict-Jmodels: two-parameter integrable models of correlated electrons

Abstract

Two new one-dimensional fermionic models depending on two independent parameters are formulated and solved exactly by the Bethe ansatz method. These models connect continuously the integrable Hubbard and supersymmetric t - J models.

A New Integrable Two-Parameter Model of Strongly Correlated Electrons in One Dimension

R. Z Bariev, A Klümper, J Zittartz

A new one-dimensional fermion model depending on two independent interaction parameters is formulated and solved exactly by the Bethe-ansatz method. The Hamiltonian of the model contains the Hubbard interaction and correlated hopping as well as pair hopping terms. The density-density and pair correlations are calculated which manifest superconducting properties in certain regimes of the phase diagram.

New Integrable Generalization of the One-Dimensional t-J Model

Francisco Castilho Alcaraz, R. Z. Bariev

A new generalization of the t-J model with a nearest-neigbour hopping is formulated and solved exactly by the Bethe-ansatz method in the thermodymanic limit. The model describes the dymanics of fermions with different spins and with isotropic and anisotropic interactions.

New Supersymmetric and Exactly Solvable Model of Correlated Electrons

Anthony J. Bracken, M. D. Gould, Jon Links +1 more

A new lattice model is presented for correlated electrons on the unrestricted ${4}^{L}$-dimensional electronic Hilbert space ${\ensuremath{\bigotimes}}_{n\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1}^{L}{\mathbf{C}}^{4}$ (where $L$ is the lattice length). It is a supersymmetric generalization of the Hubbard model, but differs from the extended Hubbard model proposed by Essler, Korepin, and Schoutens. The supersymmetry algebra of the new model is superalgebra gl(2 $|$1). The model contains one symmetry-preserving free real parameter which is the Hubbard interaction parameter $U$, and has its origin here in the one-parameter family of inequivalent typical 4-dimensional irreducible representations of gl(2 $|$1). On a one-dimensional lattice, the model is exactly solvable by the Bethe ansatz.

Integrability of supersymmetric quantum matrix models in the large-N limit

C.-W.H. Lee, S. G. Rajeev

Many physical systems like supersymmetric Yang-Mills theories are formulated as quantum matrix models. We discuss how to apply the Beth ansatz to exactly solve some supersymmetric quantum matrix models in the large-N limit. Toy models are constructed out of the one-dimensional Hubbard and t-J models as illustrations.
