Hamiltonian-versus-energy diagrams in soliton theory

Akhmediev, Nail; Ankiewicz, Adrian; Grimshaw, Roger


Parametric curves featuring Hamiltonian versus energy are useful in the theory of solitons in conservative nonintegrable systems with local nonlinearities. These curves can be constructed in various ways. We show here that it is possible to find the Hamiltonian (H) and energy (Q) for solitons of non-Kerr-law media with local nonlinearities without specific knowledge of the functional form of the soliton itself. More importantly, we show that the stability criterion for solitons can be...[Show more]
