Av. Ferrer et Ao. Caldeira, Dynamical properties of a gas of solitons in one-dimensional quantum antiferromagnets - art. no. 104425, PHYS REV B, 6410(10), 2001, pp. 4425
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 manga
nese chloride is analyzed above and below the transition temperature. The e
xistence of a dissipative regime for the soliton motion is conjectured and
its influence on the dynamical structure factor-which might be experimental
ly detected-is reported.
