Harmonic Hybrid Inflation
Federico Carta, Nicole Righi, Yvette Welling +1
We present a mechanism for realizing hybrid inflation using two axion fields with a purely non-perturbatively generated scalar potential. The structure of scalar potential is highl…

Resonant backreaction in axion inflation
Valerie Domcke, Veronica Guidetti, Yvette Welling +1
Axion inflation entails a coupling of the inflaton field to gauge fields through the Chern-Simons term. This results in a strong gauge field production during inflation, which back…
