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…
Nonlinear Dynamics of Kink Configurations: From Small to Large Kink Collisions
Aliakbar Moradi Marjaneh, Dionisio Bazeia
This study explores the scattering dynamics of kinks within a nonlinear system governed by a parameterized potential , examining the distinct behaviors of small and large k…
Scattering of kinks in scalar-field models with higher-order self-interactions
Aliakbar Moradi Marjaneh, Fabiano C. Simas, D. Bazeia
Higher-order scalar field models in two dimensions, including the model, have been researched. It has been shown that for some special cases of the minima positions of the po…
Connections between kinks with different asymptotics
Vakhid A. Gani, Aliakbar Moradi Marjaneh
In this letter, we show how to build bridges between field-theoretic models that have kink solutions with different asymptotic behavior. We study transformational properties of kin…
Phonons scattering off discrete asymmetric solitons in the absence of a Peierls-Nabarro potential
Danial Saadatmand, Aliakbar Moradi Marjaneh, Alidad Askari +1
We analyze the interaction of lattice vibrations (phonon wave-packets) with an asymmetric kink soliton initially at rest. We employ the model in one space and one time dimens…
