Abstract

We consider the exact solution of a model of correlated electrons based on the superalgebra Osp(2|2). The corresponding Bethe ansatz equations have an interesting form. We derive an expression for the ground-state energy at half filling. We also present the eigenvalue of the transfer matrix commuting with the Hamiltonian.

Exact solution to a supersymmetric Gaudin model

Julia Breiderhoff, Fabio Musso, O. Ragnisco

We investigate a special case of the Gaudin model related to the superalgebra osp(1,2). We present an exact solution to that system diagonalizing a complete set of commuting observables, and providing the corresponding eigenvectors and eigenvalues. The approach used in this paper is based on the co-algebra symmetry of the model, already known from the Calogero–Gaudin system.

G. K. Sampa, A. Lima-Santos

The Algebraic Bethe ansatz for a supersymmetric nineteen vertex-model constructed from a three-dimensional representation of the twisted quantum affine Lie superalgebra $\mathcal{U}_{q}[\mathrm{osp}(2|2)^{(2)}]$ is presented in detail. The eigenvalues and eigenvectors of the row-to-row transfer matrix are calculated and the corresponding Bethe Ansatz equations are obtained and analyzed numerically.

Igor N. Karnaukhov

A new solution of supersymmetric model of electrons with correlated hopping which generalizes those obtained earlier is formulated. The model is solved in one dimension by the Bethe ansatz. The ground state energy is calculated, and the critical exponents describing the decrease of the correlation functions on long distance are derived.

The Exact Solution of the SU(3) Hubbard Model

Buoyu Hou, Dan-Tao Peng, Rui‐Hong Yue

The Bethe ansatz equations of the 1-D SU(3) Hubbard model are systematically derived by diagonalizing the inhomogeneous transfer matrix of the XXX model. We first derive the scattering matrix of the SU(3) Hubbard model through the coordinate Bethe ansatz method. Then, with the help quantum inverse scattering method we solve the nested transfer matrix and give the eigenvalues, the eigenvectors and the Bethe ansatz equations. Finally, we obtain the exactly analytic solution for the ground state. PACS:05.20.-y; 05.50.+q; 04.20.Jb; 03.65.Fd
