Solitons emerge in various non-linear systems as stable localized configurations, behaving
in many ways like particles, from non-linear optics and condensed matter to nuclear physics …

We investigate a system described by two real scalar fields coupled with gravity in (4, 1)
dimensions in warped spacetime involving one extra dimension. The results show that the …

We consider the scattering of kinks of the sinh-deformed φ^ 4 φ 4 model, which is obtained
from the well-known φ^ 4 φ 4 model by means of the deformation procedure. Depending on …

We introduce a method to obtain deformed defects starting from a given scalar field theory
which possesses defect solutions. The procedure allows the construction of infinitely many …

We deal with a scalar field coupled to gravity in five dimensions in a warped geometry. We
investigate models described by potentials that drive the system to support thick brane …

We consider (4, 1)-dimensional branes constructed with two scalar fields ϕ and χ coupled to
a Dirac spinor field by means of a general Yukawa coupling. The equation of motion for the …

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 …

In this paper we consider a class of systems of two coupled real scalar fields in
bidimensional spacetime, the main motivation being the study of the classical or linear …

This work deals with cosmological models driven by real scalar field, described by standard
dynamics in generic spherical, flat, and hyperbolic geometries. We introduce a first-order …
