Dissipative solitons which cannot be trapped
arXiv:nlin/0607047 · doi:10.1103/PhysRevLett.97.254101
Abstract
In this paper we study the behavior of dissipative solitons in systems with high order nonlinear dissipation and show how they cannot survive under the effect of trapping potentials both of rigid wall type or asymptotically increasing ones. This provides an striking example of a soliton which cannot be trapped and only survives to the action of a weak potential.
