Exact Bethe Ansatz solution for chains with non- invariant open boundary conditions
H. J. de Vega, A. González--Ruiz
The Nested Bethe Ansatz is generalized to open and independent boundary conditions depending on two continuous and two discrete free parameters. This is used to find the exact eige…
The Highest Weight Property for the Invariant Spin Chains
H. J. de Vega, A. González--Ruiz
The generators are obtained as large spectral parameter limit of the Yang-Baxter operators in the integrable invariant vertex model. The commutation relatio…
Integrable open-boundary conditions for the supersymmetric t-J model. The quantum group invariant case
A. González-Ruiz
We consider integrable open--boundary conditions for the supersymmetric t--J model commuting with the number operator and . Four families, each one depending on two arbi…
Exact solution of the invariant quantum spin chains
H. J. de Vega, A. González--Ruiz
The Nested Bethe Ansatz is generalized to open boundary conditions. This is used to find the exact eigenvectors and eigenvalues of the vertex model with fixed open bounda…
Boundary K-matrices for the XYZ, XXZ AND XXX spin chains
H. J. de Vega, A. González--Ruiz
The general solutions for the factorization equations of the reflection matrices for the eight vertex and six vertex models (XYZ, XXZ and XXX chains) are found. The as…
Free Fermionic Elliptic Reflection Matrices and Quantum Group Invariance
R. Cuerno, A. González--Ruiz
Elliptic diagonal solutions for the reflection matrices associated to the elliptic matrix of the eight vertex free fermion model are presented. They lead through the second der…
