The spectrum of an open vertex model based on the U_q[SU(2)] at roots of unity
M. J. Martins, C. S. Melo
We study the exact solution of an -state vertex model based on the representation of the algebra at roots of unity with diagonal open boundaries. We find that the r…
Algebraic Bethe ansatz for U(1) Invariant Integrable Models: Compact and non-Compact Applications
M. J. Martins, C. S. Melo
We apply the algebraic Bethe ansatz developed in our previous paper \cite{CM} to three different families of U(1) integrable vertex models with arbitrary bond states. These sta…
Algebraic Bethe Ansatz for U(1) Invariant Integrable Models: The Method and General Results
C. S. Melo, M. J. Martins
In this work we have developed the essential tools for the algebraic Bethe ansatz solution of integrable vertex models invariant by a unique U(1) charge symmetry. The formulation i…
The Bethe ansatz approach for factorizable centrally extended S-matrices
M. J. Martins, C. S. Melo
We consider the Bethe ansatz solution of integrable models interacting through factorized -matrices based on the central extention of the symmetry. The respective…
Bethe ansatz for the XXX-S chain with non-diagonal open boundaries
C. S. Melo, G. A. P. Ribeiro, M. J. Martins
We consider the algebraic Bethe ansatz solution of the integrable and isotropic XXX-S Heisenberg chain with non-diagonal open boundaries. We show that the corresponding K-matrices…
