title = "Chain-like magnetic systems: nonlinear excitations and quantum effects",
abstract = "The presence of non-linear excitations in one-dimensional magnetic systems was already indicated about 50 years ago. It was found that, apart from the usual spinwaves, a solution of the Hamiltonian describing a ferromagnetic S = 1/2 Heisenberg system is formed by “bound” complexes of two or more spinwaves. During the last decades, there has been a renewed interest in the static and dynamic properties of this type of systems. The reason for this is twofold. First, S = 1/2 spin systems with a ferromagnetic nearest neigbor interaction form one of the most simple non-trivial infinite ensembles of interacting particles. Secondly, a number of experimental systems have been synthesized, which are very good approximations of the “idealized” theoretical model systems.",
