Holographic Dark Energy Models and Higher Order Generalizations in Dynamical Chern-Simons Modified Gravity
Antonio Pasqua, Roldao da Rocha, Surajit Chattopadhyay
Dark Energy models are here investigated and studied in the framework of the Chern-Simons modified gravity model. We bring into focus the Holographic Dark Energy (HDE) model with G…
Spherically Symmetric Thick Branes Cosmological Evolution
Alex E. Bernardini, R. T. Cavalcanti, Roldao da Rocha
Spherically symmetric time-dependent solutions for the 5D system of a scalar field canonically coupled to gravity are obtained and identified as an extension of recent results obta…
Spinor Fields Classification in Arbitrary Dimensions and New Classes of Spinor Fields on 7-Manifolds
L. Bonora, K. P. S. de Brito, Roldao da Rocha
A classification of spinor fields according to the associated bilinear covariants is constructed in arbitrary dimensions and metric signatures, generalizing Lounesto's 4D spinor fi…
Bilinear Covariants and Spinor Fields Duality in Quantum Clifford Algebras
Rafal Ablamowicz, Icaro Gonçalves, Roldao da Rocha
Classification of quantum spinor fields according to quantum bilinear covariants is introduced in a context of quantum Clifford algebras on Minkowski spacetime. Once the bilinear c…
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…
Classical Tests of General Relativity: Probing Topologically Charged Black Holes on Brane Worlds in f(R) Bulk
Roldao da Rocha, A. M. Kuerten
The perihelion precession, the deflection of light, and the radar echo delay are classical tests of General Relativity here used to probe brane world topologically charged black ho…
