Deformation of sine-Gordon two-soliton solutions in $φ^{4}$ kink-antikink configurations

Aliakbar Moradi Marjaneh, Danial Saadatmand, Fabiano C. Simas +2

In this work, we construct analytical kink-antikink $(K K ˉ)$ configurations in the non-integrable $φ^{4}$ model by mapping exact solutions of the integrable sine-Gordon system vi…

A resonance in phonons scattering off a kink in the absence of a Peierls-Nabarro potential

Danial Saadatmand, Arpine Piloyan, David Amundsen +1

We investigate the interaction of small-amplitude waves called phonons, with an initially static kink in an exceptional discretization of the $ϕ^{4}$ model that is free of the Peierl…
