Abstract

We formulate a systematic Bethe ansatz approach for computing bound-state ('breather') S matrices for integrable quantum spin chains. We use this approach to calculate the breather boundary S matrix for the open X X Z spin chain with diagonal boundary fields. We also compute the soliton boundary S matrix in the critical regime.
