Asymptotic safety and field parametrization dependence in the f(R) truncation
Gustavo P. de Brito, Nobuyoshi Ohta, Antonio D. Pereira +2
We study the dependence on field parametrization of the functional renormalization group equation in the truncation for the effective average action. We perform a systematic…

Photon gravitational defection in Lorentz violating scenarios
Antonio Accioly, Gustavo P. de Brito, José Helayël-Neto
The effect of Lorentz symmetry violation in the phenomenon of photon gravitational bending, is investigated. Using a semiclassical approach, where the photon is described by the Ca…

Interparticle potential energy for D-dimensional electromagnetic models from the corresponding scalar ones
Antonio Accioly, José Helayël-Neto, Gilson Correia +3
Using a method based on the generating functional plus a kind of "correspondence principle" --- which acts as a bridge between the electromagnetic and scalar fields --- it is shown…
