Abstract
Despite the enormous variety of quasi one-dimensional problems in which solitons seem to play a crucial role, only few well-known potentials (sine~ Gordon, double-sine-Gordon, and higher-order polynomial rnodels) have been used for modelling physical systems. It appears then relevant to look for a wider class of potentials useful to describe nonlinear excitations in real materials. ...File in questo prodotto:
