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 …

We present a comprehensive review about the various facets of kink solutions with a power
law tail, which have received considerable attention during the last few years. This area of …

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 …

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 …

Moduli spaces—finite-dimensional, collective coordinate manifolds—for kinks and antikinks
in ϕ 4 theory and sine-Gordon theory are reconsidered. The field theory Lagrangian …

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 …

Kink-antikink scattering in nonintegrable field theories like ϕ 4 theory is still rather poorly
understood beyond brute-force numerical calculations, even after several decades of …

A bstract We study the scattering processes of kink-antikink and kink-kink pairs in a field
theory model with non-differentiable potential at its minima. The kink-antikink scattering …

The asymmetric scattering between wobblers and kinks in the standard ϕ 4 model is
numerically investigated in two different scenarios. First, the collision between wobblers with …

This work deals with systems of two real scalar fields coupled to impurity functions, meant to
model inhomogeneities often encountered in real physical applications. We investigate the …
