Diagonalization of the Heun-Askey-Wilson operator, Leonard pairs and the algebraic Bethe ansatz

Pascal Baseilhac, Rodrigo A. Pimenta

An operator of Heun-Askey-Wilson type is diagonalized within the framework of the algebraic Bethe ansatz using the theory of Leonard pairs. For different specializations and the ge…

Towards the solution of an integrable $D_{2}^{(2)}$ spin chain

Rafael I. Nepomechie, Rodrigo A. Pimenta, Ana L. Retore

Two branches of integrable open quantum-group invariant $D_{n + 1}^{(2)}$ quantum spin chains are known. For one branch (epsilon=0), a complete Bethe ansatz solution has been propose…
