A method for obtaining thick branes models
A. de Souza Dutra, G. P. de Brito, J. M. Hoff da Silva
In this work we present a new class of braneworld models, where the superpotential function may be decomposed in a very specific form, but still embracing, which allows considerabl…
Hawking Radiation from Elko Particles Tunnelling across Black Strings Horizon
Roldao da Rocha, J. M. Hoff da Silva
We apply the tunnelling method for the emission and absorption of Elko particles in the event horizon of a black string solution. We show that Elko particles are emitted at the exp…
Smooth thick braneworlds and the Gibbons-Kallosh-Linde no-go theorem
Marco Dias, J. M. Hoff da Silva, Roldão da Rocha
After working out the so called braneworld sum rules formalism in order to encompass Gauss-Bonnet terms, the generation of thick branes is proposed, even with a periodic extra dime…
Classic tests of General Relativity described by brane-based spherically symmetric solutions
R. R. Cuzinatto, P. J. Pompeia, M. de Montigny +2
We discuss a way to obtain information about higher dimensions from observations by studying a brane-based spherically symmetric solution. The three classic tests of General Relati…
Some remarks on the attractor behaviour in ELKO cosmology
S. H. Pereira, A. Pinho S. S., J. M. Hoff da Silva
Recent results on the dynamical stability of a system involving the interaction of the ELKO spinor field with standard matter in the universe have been reanalysed, and the conclusi…
VSR symmetries in the DKP algebra: the interplay between Dirac and Elko spinor fields
R. T. Cavalcanti, J. M. Hoff da Silva, Roldao da Rocha
VSR symmetries are here naturally incorporated in the DKP algebra on the spin-0 and the spin-1 DKP sectors. We show that the Elko (dark) spinor fields structure plays an essential…
