Explosive particle production in non-commutative inflation
Hideki Perrier, Ruth Durrer, Massimiliano Rinaldi
We consider a model of inflation which has recently been proposed in the literature and where inflation is induced by corrections to the energy density coming from the non-commutat…
Black holes with non-minimal derivative coupling
Massimiliano Rinaldi
We study the gravitational field equations in the presence of a coupling between the derivative of a massless scalar field and the Einstein tensor. This configuration is motivated…
Fab Four: When John and George play gravitation and cosmology
Jean-Philippe Bruneton, Massimiliano Rinaldi, Antonin Kanfon +3
Scalar-tensor theories of gravitation have recently regained a great interest after the discovery of the Chameleon mechanism and of the Galileon models. The former allows, in princ…
Aspects of Quantum Gravity in Cosmology
Massimiliano Rinaldi
We review some aspects of quantum gravity in the context of cosmology. In particular, we focus on models with a phenomenology accessible to current and near-future observations, as…
