Exceptional Points, Bulk-Boundary Correspondence, and Entanglement Properties for a Dimerized Hatano-Nelson Model with Staggered Potentials
Yasamin Mardani, Rodrigo A. Pimenta, Jesko Sirker
It is well-known that the standard bulk-boundary correspondence does not hold for non-Hermitian systems in which also new phenomena such as exceptional points do occur. Here we stu…
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…
