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 …

In the general framework of Metric-Affine theories of gravity, where the metric and the
connection are independent variables, we consider actions quadratic in the Ricci scalar …

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 …

We construct a model of quintessential inflation in Palatini R 2 gravity employing a scalar
field with a simple exponential potential and coupled to gravity with a running non-minimal …

In the framework of classical scale invariance, we consider quadratic gravity in the Palatini
formalism and investigate the inflationary predictions of the theory. Our model corresponds …

We study reheating of inflationary models with general non-minimal coupling K (ϕ) R with K
(ϕ)∼√(V (ϕ)) where R is the Ricci scalar and R is the inflaton potential. In particular, when …

We study non-minimal Coleman-Weinberg inflation in the Palatini formulation of gravity in
the presence of an R 2 term. The Planck scale is dynamically generated by the vacuum …

The predictions of standard Higgs inflation in the framework of the metric formalism yield a
tensor-to-scalar ratio r∼ 10-3 which lies well within the expected accuracy of near-future …

Bimetric gravity is a theory of gravity that posits the existence of two interacting and
dynamical metric tensors. The spectrum of bimetric gravity consists of a massless and a …
