Kink-kink and kink-antikink interactions with long-range tails

IC Christov, RJ Decker, A Demirkaya, VA Gani… - Physical review …, 2019 - APS
In this Letter, we address the long-range interaction between kinks and antikinks, as well as
kinks and kinks, in φ 2 n+ 4 field theories for n> 1. The kink-antikink interaction is generically …

Long-range interactions of kinks

IC Christov, RJ Decker, A Demirkaya, VA Gani… - Physical Review D, 2019 - APS
We present a computational analysis of the long-range interactions of solitary waves in
higher-order field theories. Our vehicle of choice is the φ 8 field theory, although we explore …

Collisions of kinks in deformed φ4 and φ6 models

AM Marjaneh, FC Simas, D Bazeia - Chaos, Solitons & Fractals, 2022 - Elsevier
Two hyperbolic-deformed field theoretic models are discussed. In both of them, due to the
effect of specific deformation function on the well known φ 4 and φ 6 models, their internal …

A sufficient condition for asymptotic stability of kinks in general (1+ 1)-scalar field models

M Kowalczyk, Y Martel, C Muñoz, H Van Den Bosch - Annals of PDE, 2021 - Springer
We study stability properties of kinks for the (1+ 1)-dimensional nonlinear scalar field theory
models ∂ _t^ 2 ϕ-∂ _x^ 2 ϕ+ W'(ϕ)= 0,\quad (t, x) ∈ R * R.∂ t 2 ϕ-∂ x 2 ϕ+ W′(ϕ)= 0,(t …

Kink-antikink collisions and multi-bounce resonance windows in higher-order field theories

IC Christov, RJ Decker, A Demirkaya, VA Gani… - … in Nonlinear Science …, 2021 - Elsevier
We study collisions of coherent structures in higher-order field-theoretic models, such as the
ϕ 8, ϕ 10 and ϕ 12 ones. The main distinguishing feature, of the example models …

Collisions of weakly-bound kinks in the Christ-Lee model

P Dorey, A Gorina, T Romańczukiewicz… - Journal of High Energy …, 2023 - Springer
A bstract We investigate soliton collisions in a one-parameter family of scalar field theories in
1+ 1 dimensions which was first discussed by Christ and Lee [1]. The models have a sextic …

Four decades of kink interactions in nonlinear Klein-Gordon models: a crucial typo, recent developments and the challenges ahead

PG Kevrekidis, RH Goodman - arXiv preprint arXiv:1909.03128, 2019 - arxiv.org
The study of kink interactions in nonlinear Klein-Gordon models in $1+ 1$-dimensions has a
time-honored history. Until a few years ago, it was arguably considered a fairly mature field …

Geometrically constrained kink-like configurations engendering long-range, double-exponential, half-compact and compact behavior

D Bazeia, MA Marques, R Menezes - The European Physical Journal Plus, 2023 - Springer
We describe a procedure that contributes to modify the asymptotic behavior of kinks in a
model described by two real scalar fields. The investigation takes advantage of a first-order …

Wobbling kinks in a two-component scalar field theory: Interaction between shape modes

A Alonso-Izquierdo, D Miguélez-Caballero… - Physica D: Nonlinear …, 2023 - Elsevier
In this paper the interaction between the shape modes of the wobbling kinks arising in the
family of two-component MSTB scalar field theory models is studied. The spectrum of the …

Kinks in higher-order polynomial models

PA Blinov, TV Gani, AA Malnev, VA Gani… - Chaos, Solitons & …, 2022 - Elsevier
We consider a family of field-theoretic models with a real scalar field in (1+ 1)-dimensional
space–time. The field dynamics in each model is determined by a polynomial potential with …
