Using numerical methods, we investigate the absorption properties of a family of
nonsingular solutions which arise in different metric-affine theories, such as quadratic and …

In this work, we investigate probe scalar field models preserving covariance on fixed, static
background geometries that present hyperscaling violation properties. We develop a first …

In this paper, we study a peculiar model for the scalar field. We add the cuscuton term in a
standard model and investigate how this inclusion modifies the usual behavior of kinks. We …

This work develops a procedure to find classes of Lagrangian densities that describe
generalizations of the Abelian Maxwell–Higgs, the Chern–Simons–Higgs and the Maxwell …

We investigate the presence of magnetic monopoles in a model that extends the non-
Abelian model originally studied by't Hooft and Polyakov with the inclusion of an extra …

In this work, we deal with vortices in Maxwell-Higgs or Chern-Simons-Higgs models that
engender long range tails. We find first-order differential equations that support minimum …

We investigate the presence of vortex structures in generalized Maxwell–Higgs and Chern–
Simons–Higgs models in the three-dimensional spacetime. Despite the important difference …

We deal with the presence of magnetic monopoles in a non-Abelian model that generalizes
the standard't Hooft–Polyakov model in three spatial dimensions. We investigate the energy …

This work deals with the presence of localized static structures in the real line, described by
relativistic real scalar fields in two spacetime dimensions. We consider models featuring …

We study the stability of topological structures in generalized models with a single real
scalar field. We show that it is driven by a Sturm-Liouville equation and investigate the …
