A supersymmetric U q[osp(2—2)]-extended Hubbard model with boundary fields

A strongly correlated electron system associated with the quantum superalgebra Uq[osp(2|2)] is studied in the framework of the quantum inverse scattering method. By solving the graded reflection equation, two classes of boundary-reflection Kmatrices leading to four kinds of possible boundary interaction terms are found. Performing the algebraic Bethe ansatz, we diagonalize the two-level transfe...

Complete Solution of a Supersymmetric Extended Hubbard Model

We show that the recently constructed exact solution of the SU(2|2) extended Hub-bard model on a one-dimensional lattice provides a complete set of 4 L eigenstates of the hamiltonian, where L is the length of the lattice.

Spectrum of Low-lying Excitations in a Supersymmetric Extended Hubbard Model 1

We continue the study of the u(2j2)-supersymmetric extension of the Hubbard model in one dimension. We determine the excitation spectrum at zero temperature even in the sectors where the ground states are u(2j2)-descendants of Bethe states. The ex-citations include spinons, holons, electrons, localons (local electrons pairs, moving coherently through the lattice) and their bound states. The spe...

Exactly solvable extended Hubbard model.

One dimensional chiral Hubbard model reduces to the Haldane-Shastry spin chain at half-filling with large but finite on-site energy U . In this talk, we show that the Gutzwiller-Jastrow wavefunctions are the eigen-states of the Hubbard model at U = +∞ at less than half-filling. The full energy spectrum and an infinite set of mutually commuting constants of motion are also given in this limit fo...
