A model for the soliton-potential scattering is presented. This model is constructed with a better approximation for adding the potential to the Lagrangian through the metric of background space time. The results of the ...

Scattering properties of solitary waves of  4 model, on potentials are investigated. Soliton-potential scattering is studied with three different models. In model 1 we have added the potential through a suitable metric ...

The effect of the Phi4 kink’s internal mode (IM) during the scattering from a PT -symmetric defect is investigated. It is demonstrated that if a Phi4 kink hits the defect from the gain side, a noticeable IM is excited, while for the kink coming from...

Creation of solitons as kink–antikink pairs from particles is investigated, in the Phi4 model. Particle-like states are simulated by two widely separated identical wave trains which are propagated toward collision point from both sides in a trivial...
