Compact structures in impurity-doped vacuumless systems
I. Andrade, D. Bazeia, M. A. Marques +1
We investigate novel structures which arise from the compactification of vacuumless kinks in scalar field models coupled to impurities that preserve half the BPS sectors, described…
Magnetic monopoles in Yang-Mills-Higgs theory with impurities
D. Bazeia, M. A. Liao, M. A. Marques
In this work, BPS models built from the coupling of Yang-Mills-Higgs Lagrangian to impurities are investigated. We first consider scalar impurities, which in the BPS limit generate…
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…
Super long-range vortices
C. A. G Almeida, I. Andrade, M. A. Marques +1
In this work, we investigate the presence of vortex configurations with logarithmic tails, which we call super long-range vortices, in Maxwell-Higgs models with gauge field dynamic…
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…
