Algebraic Properties of the Bethe Ansatz for an Spl(2,1)-supersymmetric T-j Model
We investigate the algebraic structure of the supersymmetric t-J model in one dimension. We prove that the Bethe ansatz states are highest weight vectors of an spl(2,1) superalgebra. By acting with shift operators we construct a complete set of states for this model. In addition we analyse the multiplet structure of the anti-ferromagnetic ground state and some low lying excitations. It turns ou...
متن کاملDeterminant Representations of Correlation Functions for the Supersymmetric t-J Model
Working in the F-basis provided by the factorizing F-matrix, the scalar products of Bethe states for the supersymmetric t-J model are represented by determinants. By means of these results, we obtain determinant representations of correlation functions for the model.

Integrable open-boundary conditions for the supersymmetric t-J model. The quantum group invariant case. Abstract We consider integrable open–boundary conditions for the supersymmetric t–J model commuting with the number operator n and S z. Four families, each one depending on two arbitrary parameters, are found. We find the relation between Sklyanin's method of constructing open boundary condit...
متن کاملThe Supersymmetric t-J Model with a Boundary
An open supersymmetric t-J chain with boundary fields is studied by means of the Bethe Ansatz. Ground state properties for the case of an almost half-filled band and a bulk magnetic field are determined. Boundary susceptibilities are calculated as functions of the boundary fields. The effects of the boundary on excitations are investigated by constructing the exact boundary S-matrix. From the a...
