Wobbles and other kink-breather solutions of the Sine Gordon model
arXiv:0708.1088 · doi:10.1103/PhysRevE.77.036613
Abstract
We study various solutions of the Sine Gordon model in (1+1) dimensions. We use the Hirota method to construct some of them and then show that the wobble, discussed in detail by Kälberman, is one of such solutions. We concentrate our attention on a kink and its bound states with one or two breathers. We study their stability and some aspects of their scattering properties on potential wells and on fixed boundary conditions.
