Quasinormal frequencies for a black hole in a bumblebee gravity
R. Oliveira, D. M. Dantas, C. A. S. Almeida
After recent observational events like the LIGO-Virgo detections of gravitational waves and the shadow image of M87* supermassive black hole by Event Horizon Telescope (EHT), the t…
New class of solutions of a generalized -sigma Chern-Simons model
F. C. E. Lima, D. M. Dantas, C. A. S. Almeida
In this work, we investigated the existence of compacton-like configuration in the O(3)-sigma model. We consider a minimally coupled O(3)-sigma model with a gauge field governed by…

R. V. Maluf, D. M. Dantas, C. A. S. Almeida
In this work, we obtain the Casimir energy for the real scalar field and the Elko neutral spinor field in a field theory at a Lifshitz fixed point (LP). We analyze the massless and…
Quasi-normal modes of bumblebee wormhole
R. Oliveira, D. M. Dantas, Victor Santos +1
In this work, we calculate the quasi-normal frequencies from a bumblebee traversable wormhole. The bumblebee wormhole model is based on the bumblebee gravity, which exhibits a spon…
Configurational entropy and Newton's Law in double sine-Gordon braneworlds
W. T. Cruz, D. M. Dantas, R. V. Maluf +1
In this work, we evaluate the Shannon-like entropic measure of spatially-localized functions for a five-dimensional braneworld generated by a double sine-Gordon (DSG) potential. Th…
Corrections to Newton's law of gravitation - application to hybrid Bloch brane
C A S Almeida, D F S Veras, D M Dantas
We present in this work, the calculations of corrections in the Newton's law of gravitation due to Kaluza-Klein gravitons in five-dimensional warped thick braneworld scenarios. We…
Monopoles on string-like models and the Coulomb's law
D. M. Dantas, R. da Rocha, C. A. S. Almeida
The t'Hooft-Polyakov monopole mass can be substantially altered, in the thick GS and HC brane-world setup, and can be employed to constrain the brane thickness limit. In this work,…

W. T. Cruz, D. M. Dantas, R. A. C. Correa +1
The so-called configurational entropy (CE) framework has proved to be an efficient instrument to study nonlinear scalar field models featuring solutions with spatially-localized en…
Graviton KK resonant mode in the correction of the Newton's law from 6D braneworlds
J. C. B. Araujo, D. F. S. Veras, D. M. Dantas +1
In this work, we derive an expression for the correction in the Newton's law of gravitation due to the gravitational Kaluza-Klein states in a general thick string-like braneworld s…
Refinements of the Weyl pure geometrical thick branes from information-entropic measure
R. A. C. Correa, D. M. Dantas, P. H. R. S. Moraes +2
This letter aims to analyse the so-called configurational entropy in the Weyl pure geometrical thick brane model. The Weyl structure plays a prominent role in the thickness of this…

R. A. C. Correa, D. M. Dantas, C. A. S. Almeida +1
In this work we obtain bounds on the topological Abelian string-vortex and on the string-cigar, by using a new measure of configurational complexity, known as configurational entro…

We analyse the trapping of eigenspinors of the charge conjugation operator with dual helicity (Elko), in thin and thick string-like models with codimension-2. Elko spinor fields de…

D. M. Dantas, D. F. S. Veras, J. E. G. Silva +1
We study the spin 1/2 and spin 3/2 fermion fields in a thick braneworld scenario in six dimensions called string-cigar model. This smooth string-like model has a source that satisf…
Vector and fermion fields on a bouncing brane with a decreasing warp factor in a string-like defect
L. J. S. Sousa, C. A. S. Silva, D. M. Dantas +1
In a recent work, a model has been proposed where a brane is made of a scalar field with bounce-type configurations and embedded in a bulk with a string-like metric. This model pro…
Fermions in a warped resolved conifold
D. M. Dantas, J. E. G. Silva, C. A. S. Almeida
We investigated the localization of the spinorial field in a braneworld built as a warped product between a 3-brane and a 2-cycle of the resolved conifold. This scenario provides a…
