摘要
The influence of the soliton-magnon coupling on the dynamical properties of quantum antiferromagnets is studied as a function of the external magnetic field and the temperature. The specific case of tetramethyl ammonium manganese chloride is analyzed above and below the transition temperature. The existence of a dissipative regime for the soliton motion is conjectured and its influence on the dynamical structure factor-which might be experimentally detected-is reported.
