Evolution of Large Scale Curvature Fluctuations During the Perturbative Decay of the Inflaton
F. Di Marco, F. Finelli, A. Gruppuso
We study the evolution of cosmological fluctuations during and after inflation driven by a scalar field coupled to a perfect fluid through afriction term. During the slow-roll regi…
"Graceful" Old Inflation
Fabrizio Di Marco, Alessio Notari
We show that Inflation in a False Vacuum becomes viable in the presence of a spectator scalar field non minimally coupled to gravity. The field is unstable in this background, it g…
Slow-roll Inflation for Generalized Two-Field Lagrangians
Fabrizio Di Marco, Fabio Finelli
We study the slow-roll regime of two field inflation, in which the two fields are also coupled through their kinetic terms. Such Lagrangians are motivated by particle physics and b…
Adiabatic and Isocurvature Perturbations for Multifield Generalized Einstein Models
Fabrizio Di Marco, Fabio Finelli, Robert Brandenberger
Low energy effective field theories motivated by string theory will likely contain several scalar moduli fields which will be relevant to early Universe cosmology. Some of these fi…
