Transforming kinks into compactons in the O (3)-sigma model
FCE Lima, DA Gomes, CAS Almeida - Annals of Physics, 2020 - Elsevier
In this work, we investigate the solutions of vortices in the O (3)-sigma model with the gauge
field governed by the Chern–Simons term and subject to a hyperbolic self-dual potential. We …

Kinks and branes in models with hyperbolic interactions
In this work, we investigate several models described by a single real scalar field with
nonpolynomial interactions, constructed to support topological solutions. We do this using …

A new class of solutions of a generalized O (3)-sigma Chern-Simons model
In this work, we investigated the existence of compacton-like configuration in the O (3)-sigma
model. We consider a minimally coupled O (3)-sigma model with a gauge field governed by …

Kinklike structures in models of the Dirac–Born–Infeld type
The present work investigates several models of a single real scalar field, engendering
kinetic term of the Dirac–Born–Infeld type. Such theories introduce nonlinearities to the …

The possibility of tachyons as soliton solutions in 3+ 1 dimensions via k-field models
M Mohammadi - Annals of Physics, 2024 - Elsevier
Tachyons or hypothetical faster-than-light (FTL) particles would fail the principle of causality.
Such particles may only be imagined when they have no energy and momentum and, thus …

Ring-like vortices in a logarithmic generalized Maxwell theory
FCE Lima, CAS Almeida - Europhysics Letters, 2020 - iopscience.iop.org
We investigate the presence of vortex structures in a Maxwell model with a logarithmic
generalization. This generalization becomes important because it generates stationary field …
