Abstract

The dynamics and statistical mechanics of two-parametric solitons (dyons) in a weakly nonuniaxial Heisenberg antiferromagnetic chain are considered. The dyon contribution to the dynamic structure factor is calculated, and resonance frequencies for the recently studied 1D antiferromagnet CsMn $I_{3}$ are estimated.
