Towards the solution of an integrable spin chain
Rafael I. Nepomechie, Rodrigo A. Pimenta, Ana L. Retore
Two branches of integrable open quantum-group invariant quantum spin chains are known. For one branch (epsilon=0), a complete Bethe ansatz solution has been propose…

New D_{n+1}^(2) K-matrices with quantum group symmetry
Rafael I. Nepomechie, Rodrigo A. Pimenta
We find new families of solutions of the boundary Yang-Baxter equation. The open spin-chain transfer matrices constructed with these K-matrices have quantum group s…

Fusion for AdS/CFT boundary S-matrices
Rafael I. Nepomechie, Rodrigo A. Pimenta
We propose a fusion formula for AdS/CFT worldsheet boundary S-matrices. We show that, starting from the fundamental Y=0 boundary S-matrix, this formula correctly reproduces the two…
