Abstract
The essentials of a Sine-Gordon gas are briefly indicated. The mapping of an antiferromagnetic chain with orthorhombic symmetry on the Sine-Gordon system is analyzed in detail. The Sine-Gordon profile for the static domain wall is found to linearly stable. In this analysis it became clear that the hard axis switching has to be treated carefully. The agreement between experimental data on the spin-spin correlation function, the specific heat and the thermal conductivity is discussed.
