Reheating via a generalized non-minimal coupling of curvature to matter
Orfeu Bertolami, Pedro Frazão, Jorge Páramos
In this work one shows that a generalized non-minimal coupling between geometry and matter is compatible with Starobinsky inflation and leads to a successful process of preheating,…
Using global positioning systems to test extensions of General Relativity
O. Bertolami, J. Páramos
We consider the feasibility of using the Galileo Navigation Satellite System to constrain possible extensions or modifications to General Relativity, by assessing the impact of the…
Dark matter as a dynamic effect due to a non-minimal gravitational coupling with matter
Orfeu Bertolami, Jorge Páramos
In this work the phenomenology of models possessing a non-minimal coupling between matter and geometry is discussed, with a particular focus on the possibility of describing the fl…
Accelerated expansion from a non-minimal gravitational coupling to matter
O. Bertolami, P. Frazao, J. Páramos
It is shown that a non-minimal coupling between the scalar curvature and the matter Lagrangian density may account for the accelerated expansion of the Universe and provide, throug…
