Exact solutions for a complex scalar field under discrete symmetry
D. Bazeia, R. Menezes, G. S. Santiago
We report on the presence of families of exact solutions for a complex scalar field that behaves according to the rules of discrete symmetry. Since the family of models is ex…
Generalized scalar field models in the presence of impurities
D. Bazeia, M. A. Marques, R. Menezes
We study generalized scalar field models coupled to impurities in Minkowski spacetime with arbitrary dimensions. The investigation concerns a class of models that depends explicitl…
New brane-like solutions in modified four-dimensional Einstein-Gauss-Bonnet gravity
D. Bazeia, R. Menezes, A. Yu. Petrov +1
We investigate solutions of a new Einstein-Gauss-Bonnet gravity ( ). We first describe the bulk vacuum solution, then we add a massive probe scalar field, and we foll…
Radially symmetric scalar field solutions in the presence of cuscuton term
D. Bazeia, M. A. Marques, R. Menezes +1
In this work, we investigate radially symmetric solutions in arbitrary dimensions in scalar field models in the presence of the cuscuton term. We introduce a first-order formalism…
Scalar fields with impurities in arbitrary dimensions: first-order framework and exact solutions
D. Bazeia, M. A. Marques, R. Menezes
We study a class of scalar field models coupled to impurities in arbitrary spacetime dimensions. The system admits the introduction of a second-order tensor that can be forced to o…
Braneworlds in bumblebee gravity
M. A. Marques, R. Menezes, A. Yu. Petrov +1
We investigate thick-brane solutions within the five-dimensional bumblebee gravity in the presence of a real scalar field. Specifically, we implement the Lorentz symmetry breaking…
