We review the main aspects of the warm inflation scenario, focusing on the inflationary
dynamics and the predictions related to the primordial spectrum of perturbations, to be …

The past two decades have seen transformative advances in cosmology and string theory.
Observations of the cosmic microwave background have revealed strong evidence for …

An important unsolved problem that affects practically all attempts to connect string theory to
cosmology and phenomenology is how to distinguish effective field theories belonging to the …

The computation of the primordial power spectrum in multi-field inflation models requires us
to correctly account for all relevant interactions between adiabatic and non-adiabatic modes …

We forecast the scientific capabilities to improve our understanding of cosmic inflation of
CORE, a proposed CMB space satellite submitted in response to the ESA fifth call for a …

We propose an alternative refined de Sitter conjecture. It is given by a natural condition on a
combination of the first and second derivatives of the scalar potential. We derive our …

We present an overview of inflationary models derived from string theory focusing mostly on
closed string moduli as inflatons. After a detailed discussion of the η-problem and different …

We introduce a simple string model of inflation, in which the inflaton field can take trans-
Planckian values while driving a period of slow-roll inflation. This leads naturally to a …

We compute the low energy effective field theory (EFT) expansion for singlefield inflationary
models that descend from a parent theory containing multiple other scalar fields. By …
