Flat and bent branes in Born-Infeld-like scalar field models
I. Andrade, M. A. Marques, R. Menezes
In this work, we investigate the presence of thick branes modeled by a single scalar field with Born-Infeld-like dynamics. We consider the 4-dimensional metric being Minkowski, de…
Impurity-doped stable domain walls in spherically symmetric spacetimes
D. Bazeia, M. A. Liao, M. A. Marques
In this work, radially symmetric kink-like solutions in the presence of impurities are investigated for both flat and curved spacetimes, with geometry generated by a rotation…
Impurity-doped scalar fields in arbitrary dimensions
D. Bazeia, M. A. Liao, M. A. Marques
We investigate the presence of localized structures for relativistic scalar fields coupled to impurities in arbitrary spatial dimensions. Such systems present spatial inhomogeneity…
Geometrically constrained multifield models with BNRT solutions
M. A. Marques, R. Menezes
In this paper, we investigate multifield models in which the two-field BNRT model is coupled to a third field through mediator functions in the Lagrangian density. To conduct the i…
Geometrically constrained kinklike configurations engendering long range, double exponential, half-compact and compact behavior
D. Bazeia, M. A. Marques, R. Menezes
We describe a procedure that contributes to modify the asymptotic behavior of kinks in a model described by two real scalar fields. The investigation takes advantage of a first ord…
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…
