Multi-Magnon Scattering in the Ferromagnetic XXX-Model with Inhomogeneities
arXiv:cond-mat/9710055 · doi:10.1088/0305-4470/31/7/004
Abstract
We determine the transition amplitude for multi-magnon scattering induced through an inhomogeneous distribution of the coupling constant in the ferromagnetic XXX-model. The two and three particle amplitudes are explicitely calculated at small momenta. This suggests a rather plausible conjecture also for a formula of the general n-particle amplitude.
