چکیده
We study the generalized supersymmetric t−J model with boundaries. Starting from the trigonometric R-matrix, and in the framework of the graded quantum inverse scattering method (QISM), we obtain the eigenvalues and Bethe ansatz equations of the supersymmetric t−J model with boundaries in three different backgrounds. PACS: 75.10.Jm, 71.10.Fd, 05.30.Fk.

Exact diagonalization of the generalized supersymmetric t − J model with boundaries
We study the generalized supersymmetric t−J model with boundaries in three different gradings: FFB, BFF and FBF. Starting from the trigonometric R-matrix, and in the framework of the graded quantum inverse scattering method (QISM), we solve the eigenvalue problems for the supersymmetric t−J model. A detailed calculations are presented to obtain the eigenvalues and Bethe ansatz equations of the ...

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...

We use the algebraic nested Bethe ansatz to solve the eigenvalue and eigenvector problem of the supersymmetric SUq(n|m) model with open boundary conditions. Under an additional condition that model is related to a multicomponent supersymmetric t-J model. We also prove that the transfer matrix with open boundary condition is SUq(n|m) invariant.

We show that instantons violate a supersymmetric identity in a classically supersymmetric Higgs model with no massless fermions. This anomalous breaking arises because the correct perturbative expansion in the instanton sector is not supersymmetric. The attempt to construct a manifestly supersymmetric expansion generates infra-red divergences.
