1 J ul 1 99 9 Boundary Kondo impurities in the generalized supersymmetric t − J model
We study the generalized supersymmetric t − J model with Kondo impurities in the boundaries. We first construct the higher spin operator K-matrix for the XXZ Heisenberg chain. Setting the boundary parameter to be a special value, we find a higher spin reflecting K-matrix for the supersymmetric t− J model. By using the Quantum Inverse Scattering Method, we obtain the eigenvalue and the correspon...
متن کاملIntegrable boundary impurities in the t − J model with different gradings
We investigate the generalized supersymmetric t− J model with boundary impurities in different gradings. All three different gradings: fermion, fermion, boson (FFB), boson, fermion, fermion (BFF) and fermion, boson, fermion (FBF), are studied for the generalized supersymmetric t − J model. Boundary K-matrix operators are found for the different gradings. By using the graded algebraic Bethe ansa...
متن کاملINTEGRABILITY OF A t− J MODEL WITH IMPURITIES
A t− J model for correlated electrons with impurities is proposed. The impurities are introduced in such a way that integrability of the model in one dimension is not violated. The algebraic Bethe ansatz solution of the model is also given and it is shown that the Bethe states are highest weight states with respect to the supersymmetry algebra gl(2|1). PACS: 03.65.Fd, 05.50+q, 71.20.Ad

متن کاملq-deformed supersymmetric t-J model with a boundary
The q-deformed supersymmetric t-J model on a semi-infinite lattice is diagonalized by using the level-one vertex operators of the quantum affine superalgebra Uq[ ̂ sl(2|1)]. We give the bosonization of the boundary states. We give an integral expression of the correlation functions of the boundary model, and derive the difference equations which they satisfy.
