The properties of the recently discovered Higgs boson together with the absence of new
physics at collider experiments allows us to speculate about consistently extending the …

In this paper, we present an introduction to cosmic inflation in the framework of Palatini
gravity, which provides an intriguing alternative to the conventional metric formulation of …

The current flow of high accuracy astrophysical data, among which are the Cosmic
Microwave Background (CMB) measurements by the Planck satellite, offers an …

General relativity (GR) exists in different formulations, which are equivalent in pure gravity.
Once matter is included, however, observable predictions generically depend on the version …

General relativity (GR) exists in different formulations. They are equivalent in pure gravity but
generically lead to distinct predictions once matter is included. After a brief overview of …

The Starobinsky model, considered in the framework of the Palatini formalism, in contrast to
the metric formulation, does not provide us with a model for inflation, due to the absence of a …

We study the details of preheating in Palatini Higgs inflation. We show, that contrary to what
happens in the metric formulation of the model, the Universe does not reheat through the …

We consider R 2 inflation in the Palatini gravity assuming the existence of scalar fields
coupled to gravity in the most general manner. These theories, in the Einstein frame, and for …

We make use of classical lattice simulations in 3+ 1 dimensions to study the preheating
stage of Higgs Inflation in Einstein-Cartan gravity. Focusing for concreteness on a simplified …

We study scalar field inflation in F (R) gravity in the Palatini formulation of general relativity.
Unlike in the metric formulation, in the Palatini formulation F (R) gravity does not introduce …
