Boundary energy of the general open XXZ chain at roots of unity
Rajan Murgan, Rafael I. Nepomechie, Chi Shi
We have recently proposed a Bethe Ansatz solution of the open spin-1/2 XXZ quantum spin chain with general integrable boundary terms (containing six free boundary parameters) at ro…
Exact solution of the open XXZ chain with general integrable boundary terms at roots of unity
Rajan Murgan, Rafael I. Nepomechie, Chi Shi
We propose a Bethe-Ansatz-type solution of the open spin-1/2 integrable XXZ quantum spin chain with general integrable boundary terms and bulk anisotropy values i π/(p+1), where p…
Boundary energy of the open XXZ chain from new exact solutions
Rajan Murgan, Rafael I. Nepomechie, Chi Shi
Bethe Ansatz solutions of the open spin-1/2 integrable XXZ quantum spin chain at roots of unity with nondiagonal boundary terms containing two free boundary parameters have recentl…
