Solitonmagnon bound states in TMMC above and below TN
J.A. Hołyst 1,2 H. Benner 2The problem of soliton-magnon bound states occuring in the quasi-one-dimensional antiferromagnet TMMC [(CH3)4NMnCl3] is studied. Above TN we found a bound state which is due to out-of-plane spin components when going beyond the sine-Gordon limit. Below TN we found a bound state which is originates from the pairing of ¶-kinks described by a double sine-Gordon equation.
