Split Q-Balls
D. Bazeia, L. Losano, M. A. Marques +1
We investigate the presence of non-topological solutions of the Q-ball type in (1, 1) spacetime dimensions. The model engenders the global U(1) symmetry and is of the k-field type,…
Compact Vortices
D. Bazeia, L. Losano, M. A. Marques +2
We study a family of Maxwell-Higgs models, described by the inclusion of a function of the scalar field that represent generalized magnetic permeability. We search for vortex confi…
Interface networks in models of competing alliances
T. A. Pereira, J. Menezes, L. Losano
We study a subclass of the May-Leonard stochastic model with an arbitrary, even number of species, leading to the arising of two competing partnerships where individuals are indist…
Localized four-dimensional gravity in the D-brane background with NS field
R. C. Fonseca, F. A. Brito, L. Losano
We calculate small correction terms to gravitational potential near -branes embedded in a constant NS field background in the context of M-theory or string theory. The norma…
Hybrid Bloch Brane
D. Bazeia, Elisama E. M. Lima, L. Losano
This work reports on models described by two real scalar fields coupled with gravity in the five-dimensional spacetime, with a warped geometry involving one infinite extra dimensio…
Geodesically complete BTZ-type solutions of Born-Infeld gravity
D. Bazeia, L. Losano, Gonzalo J. Olmo +1
We study Born-Infeld gravity coupled to a static, nonrotating electric field in dimensions and find exact analytical solutions. Two families of such solutions represent geode…
