A family of scalar-Einstein and vacuum Brans-Dicke axisymmetric solutions
Bertrand Chauvineau
A new method is proposed, that establishes a one to one correspondance between the whole set of static axially symmetric vacuum GR solutions and a specific class of stationary axia…
On gravitational radiation in Brans-Dicke gravity
Bertrand Chauvineau
Brans-Dicke gravity admits spherical solutions describing naked singularities rather than black holes. Depending on some parameters entering such a solution, stable circular orbits…
New views on classical and quantum Brans-Dicke theory
Júlio C. Fabris, Bertrand Chauvineau, Davi C. Rodrigues +2
The Brans-Dicke action is one of the most natural extensions of the Einstein-Hilbert action. It is based on the introduction of a fundamental scalar field that effectively incorpor…
Introducing quantum effects in classical theories
J. C. Fabris, O. F. Piattella, D. C. Rodrigues +2
In this paper, we explore two different ways of implementing quantum effects in a classical structure. The first one is through an external field. The other one is modifying the cl…
Scalar-Tensor gravity with system-dependent potential and its relation with Renormalization Group extended General Relativity
Davi C. Rodrigues, Bertrand Chauvineau, Oliver F. Piattella
We show that Renormalization Group extensions of the Einstein-Hilbert action for large scale physics are not, in general, a particular case of standard Scalar-Tensor (ST) gravity.…
Scalar-tensor theories with an external scalar
Bertrand Chauvineau, Davi C. Rodrigues, Júlio C. Fabris
Scalar-tensor (ST) gravity is considered in the case where the scalar is an external field. We show that General Relativity (GR) and usual ST gravity are particular cases of the Ex…
