Inflation and Reheating through an Independent Affine Connection
Alberto Salvio
This paper is based on a talk in which I discussed how a component of the dynamical affine connection, that is independent of the metric, can drive inflation in agreement with obse…
(Multi-field) Natural Inflation and Gravitational Waves
Alberto Salvio, Simone Sciusco
We provide a detailed study of natural inflation with a periodic non-minimal coupling, which is a well-motivated inflationary model that admits an explicit UV completion. We demons…
Supercooling in Radiative Symmetry Breaking: Theory Extensions, Gravitational Wave Detection and Primordial Black Holes
Alberto Salvio
First-order phase transitions, which take place when the symmetries are predominantly broken (and masses are then generated) through radiative corrections, produce observable gravi…
Model-Independent Radiative Symmetry Breaking and Gravitational Waves
Alberto Salvio
Models where symmetries are predominantly broken (and masses are then generated) through radiative corrections typically produce strong first-order phase transitions with a period…
