Deformation of sine-Gordon two-soliton solutions in kink-antikink configurations
Aliakbar Moradi Marjaneh, Danial Saadatmand, Fabiano C. Simas +2
In this work, we construct analytical kink-antikink configurations in the non-integrable 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 model that is free of the Peierl…
False-vacuum bubbles in sphaleron scattering
Manuel A. Martínez Sánchez, Christoph Adam, Danial Saadatmand
We investigate the collision dynamics of two bright sphalerons in a (1+1)-dimensional deformed scalar field theory with a symmetric potential possessing false vacua. Two one-…
