Degeneracy and Kink Scattering in a Two Coupled Scalar Field Model in (1,1) Dimensions

In this work, we consider the model of two coupled scalar fields φ, χ in (1, 1) dimensions introduced by D. Bazeia, M. J. dos Santos, and R. F. Ribeiro, Phys. Lett. A 208, 84 (1995). The model has a

Semi-compactness and multiple oscillating pulses in kink scattering

In this work we consider models of asymmetric kinks, where the behavior of the solution in one side is different from the other side. Also, the models depend of an integer n and, with the increase of

Collision, mechanism, and $Z_4$ operation among chiral and nonchiral kinks in coupled double-field $\phi^4$ model

Abstract: In this work, we investigate collision processes and their mechanism among chiral and nonchiral kinks in the coupled double-field φ4 model, and show that the kink collisions follow the Z4

Solitary oscillations and multiple antikink-kink pairs in the double sine-Gordon model

We study kink-antikink collisions in a particular case of the double sine-Gordon model depending on only one parameter r. The scattering process of large kink-antikink shows the changing of the

Collision of two kinks with inner structure

In this work, we study kink collisions in a scalar field model with scalar-kinetic coupling. This model supports kink/antikink solutions with inner structure in the energy density. The collision of

Collision of two kinks with inner structure

In this work, we study kink collisions in a scalar field model with scalar-kinetic coupling. This model supports kink/antikink solutions with inner structure in the energy density. The collision of

Kink-antikink collision in the supersymmetric 𝜙4 model

This paper investigates a model containing 𝜙4 kinks interacting with fermions. The fermion back-reaction is included in the equations of motion, which affects the kink-antikink collisions. We show

Resonance structures in coupled two-componentϕ4model

We present a numerical study of the process of the kink-antikink collisions in the coupled one-dimensional two-component $\phi^4$ model. Our results reveal two different soliton solutions which

Kink excitation spectra in the (1+1)-dimensional φ8 model

A bstractWe study excitation spectra of BPS-saturated topological solutions — the kinks — of the φ8 scalar field model in (1 + 1) dimensions, for three different choices of the model parameters. We

Kink–Antikink Scattering in φ4 and ϕ6 Models

For kink–antikink scattering within the φ4 non-linear field theory in one space and one time dimension resonance type configurations emerge when the relative velocity between kink and antikink falls

Quantum-induced interactions in the moduli space of degenerate BPS domain walls

A bstractIn this paper quantum effects are investigated in a very special two-scalar field model having a moduli space of BPS topological defects. In a (1 + 1)-dimensional space-time the defects are

BPS and non-BPS kinks in a massive non-linear S**2-sigma model

The stability of the topological kinks of the nonlinear S{sup 2}-sigma model discovered by Alonso Izquierdo et al. is discussed by means of a direct estimation of the spectra of the second-order

Scattering of kinks in a non-polynomial model

We study a model described by a single real scalar field in the two-dimensional space-time. The model is specified by a potential which is non-polynomial and supports analytical kink-like solutions

Fluxons in a triangular set of coupled long Josephson junctions

We report results of an analysis of the dynamics of magnetic flux solitons in the system of three long Josephson junctions between three bulk superconductors that form a prism. The system is modeled

Resonant kink-impurity interactions in the sine-Gordon model.

It is demonstrated that the SG kink may be totally reflected by an attractive impurity if its initial velocity is in some resonance windows and this effect can be predicted by a suitable collective-coordinate method and the resonance structures can be explained with an energy exchange between the kink translational mode and the impurity mode.

Multi-kink collisions in the ϕ6 model

A bstractWe study simultaneous collisions of two, three, and four kinks and antikinks of the ϕ6 model at the same spatial point. Unlike the ϕ4 kinks, the ϕ6 kinks are asymmetric and this enriches the
