Super long-range kinks
I. Andrade, M. A. Marques, R. Menezes
In this work we investigate the presence of scalar field models supporting kink solutions with logarithmic tails, which we call super long-range structures. We first consider model…
Analytical solutions for Maxwell-scalar system on radially symmetric spacetimes
I. Andrade, D. Bazeia, M. A. Marques +2
We investigate Maxwell-scalar models on radially symmetric spacetimes in which the gauge and scalar fields are coupled via the electric permittivity. We find the conditions that al…
Two-field models in the presence of impurities
D. Bazeia, M. A. Liao, M. A. Marques
This work deals with systems of two real scalar fields coupled to impurity functions, meant to model inhomogeneities often encountered in real physical applications. We investigate…
Analytical short- and long-range kink-like structures in scalar field models with polynomial interactions
I. Andrade, M. A. Marques, R. Menezes
We investigate a class of scalar field models which engender kink-like solutions in the presence of polynomial potentials that allows for modifications of the tails of the localize…
Hybrid branes from split kinks
D. Bazeia, A. S. Lobão, M. A. Marques
In this work, we investigate braneworld models generated by scalar fields in which one field has a split kink profile, in which a kink separates into two kinklike configurations. O…
Spatially localized scalar structures on hyperscaling violating geometries
I. Andrade, M. A. Marques, R. Menezes +1
In this work, we investigate probe scalar field models preserving covariance on fixed, static background geometries that present hyperscaling violation properties. We develop a fir…
