Classification of Theories Of Inflation And The Uniqueness of Starobinsky Model
Marco Piva
We classify theories using a mathematical analogy between slow-roll inflation and the renormalization-group flow. We derive the power spectra and spectral indices class by c…

Power Spectra in Double-Field Inflation Using Renormalization-Group Techniques
Bohdan Grzadkowski, Marco Piva
A perturbative strategy for inflation described by two-inflaton fields is developed using a mathematical analogy with the renormalization-group. Two small quantities, and …
