Strong Deflection Limit Lensing Effects in the Minimal Geometric Deformation and Casadio-Fabbri-Mazzacurati Solutions
R. T. Cavalcanti, A. Goncalves da Silva, Roldao da Rocha
In this paper we apply the strong deflection limit approach to investigate the gravitational lensing phenomena beyond general relativity. This is accomplished by considering the le…
Flag-dipole and flagpole spinors fluid flows in Kerr spacetimes
Roldao da Rocha, R. T. Cavalcanti
Flagpole and flag-dipole spinors are particular classes of spinor fields that has been recently used in different branches of theoretical physics. In this paper, we study the possi…
Fluid/gravity correspondence and the CFM black brane solutions
Roberto Casadio, Rogerio T. Cavalcanti, Roldao da Rocha
We consider the lower bound for the shear viscosity-to-entropy density ratio, obtained from the fluid/gravity correspondence, in order to constrain the post-Newtonian parameter of…
