Algebraic Bethe ansatz for the quantum group invariant open XXZ chain at roots of unity
For generic values of q, all the eigenvectors of the transfer matrix of the Uqsl(2)-invariant open spin-1/2 XXZ chain with finite length N can be constructed using the algebraic Bethe ansatz (ABA) formalism of Sklyanin. However, when q is a root of unity (q=eiπ/p with integer p≥2), the Bethe equatio...
