We examine the one-dimensional antiferromagnet, with a small Dzyaloshinski--Moriya component to the exchange, in a symmetry-breaking magnetic field. In the classical, continuum limit, this system is shown to obey a double sine-Gordon field theory which supports nonlinear, soliton excitations as well as linear, spin waves. We examine the dynamic spin-spin correlation function. We find the contributions coming from the nonlinear soliton excitations and the contributions from the quantized linear excitations. The quantized spin waves produce nonlinear contributions to the correlation functions that exhibit qualitative similarities to the soliton contributions.
