Collective Coordinate Model of Kink-Antikink Collisions in Theory

NS Manton, K Oleś, T Romańczukiewicz… - Physical Review Letters, 2021 - APS
The fractal velocity pattern in symmetric kink-antikink collisions in ϕ 4 theory is shown to
emerge from a dynamical model with two effective moduli: the kink-antikink separation and …

Multikink scattering in the model revisited

C Adam, P Dorey, AG Martin-Caro, M Huidobro, K Oles… - Physical Review D, 2022 - APS
Antikink-kink (K¯ K) collisions in the ϕ 6 model exhibit resonant scattering although the ϕ 6
kinks do not support any bound states to which energy could be transferred. In P. Dorey et …

Scattering between wobbling kinks

A Alonso Izquierdo, J Queiroga-Nunes, LM Nieto - Physical Review D, 2021 - APS
In this paper the scattering between a wobbling kink and a wobbling antikink in the standard
ϕ 4 model is numerically investigated. The dependence of the final velocities, wobbling …

Relativistic moduli space for kink collisions

C Adam, NS Manton, K Oles, T Romanczukiewicz… - Physical Review D, 2022 - APS
The moduli space approximation to kink dynamics permits a relativistic generalization if the
Derrick scaling parameter is used as a collective coordinate. We develop a perturbative …

Spectral walls in multifield kink dynamics

C Adam, K Oles, T Romanczukiewicz… - Journal of High Energy …, 2021 - Springer
A bstract We show that spectral walls are common phenomena in the dynamics of kinks in
(1+ 1) dimensions. They occur in models based on two or more scalar fields with a …

[HTML][HTML] Kink solutions in generalized 2D dilaton gravity

Y Zhong, H Guo, YX Liu - Physics Letters B, 2024 - Elsevier
We study static kink solutions in a generalized two-dimensional dilaton gravity model, where
the kinetic term of the dilaton is generalized to be an arbitrary function of the canonical one …

Collective coordinate models for 2-vortex shape mode dynamics

A Alonso Izquierdo, NS Manton, J Mateos Guilarte… - Physical Review D, 2024 - APS
Models are developed for the motion of charge-2 Abelian Higgs vortices through the 2-
vortex moduli space M, with the vortices excited by their shape mode oscillations. The …

Fermionic spectral walls in kink collisions

JGF Campos, A Mohammadi, JM Queiruga… - Journal of High Energy …, 2023 - Springer
A bstract We show that a spectral wall, ie, an obstacle in the dynamics of a bosonic soliton,
which arises due to the transition of a normal mode into the continuum spectrum, exists after …

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 …

Spectral walls in antikink-kink scattering in the model

C Adam, K Oles, T Romanczukiewicz, A Wereszczynski - Physical Review D, 2022 - APS
We show that thick spectral walls exist in antikink-kink collisions in the ϕ 6 model. In this
model, they are triggered by the so-called delocalized modes that do not exist in the single …
