Modified rational six vertex model on the rectangular lattice
S. Belliard, R. A. Pimenta, N. A. Slavnov
We consider a rational six vertex model on a rectangular lattice with boundary conditions that generalize the usual domain wall type. We find that the partition function of the inh…

Algebraic Bethe ansatz for 19-vertex models with upper triangular K-matrices
R. A. Pimenta, A. Lima-Santos
By means of an algebraic Bethe ansatz approach we study the Zamolodchikov-Fateev and Izergin-Korepin vertex models with non-diagonal boundaries, characterized by reflection matrice…

Algebraic Bethe ansatz for the six vertex model with upper triangular -matrices
R. A. Pimenta, A. Lima-Santos
We consider a formulation of the algebraic Bethe ansatz for the six vertex model with non-diagonal open boundaries. Specifically, we study the case where both left and right -ma…
