On the stability of scale-invariant black holes
Simon Boudet, Massimiliano Rinaldi, Samuele Marco Silveravalle
Quadratic scale-invariant gravity non minimally coupled to a scalar field provides a competitive model for inflation, characterized by the transition from an unstable to a stable f…
The phase diagram of Einstein-Weyl gravity
Samuele Silveravalle, Alessandro Zuccotti
Thanks to their interpretation as first order correction of General Relativity at high energies, quadratic theories of gravity gained much attention in recent times. Particular att…
Non-symmetric wormholes and localized Big Rip singularities in Einstein-Weyl gravity
Alfio Bonanno, Samuele Silveravalle, Alessandro Zuccotti
The inclusion of the Weyl squared term in the gravitational action is one of the most simple, yet non trivial modifications to General Relativity at high energies. Nevertheless the…
The gravitational field of isolated objects in quadratic gravity
Samuele Silveravalle
When describing gravity at high energies it is natural to introduce terms quadratic in the curvature as first corrections to the Einstein-Hilbert action. Static, spherically symmet…
