Composite Dissipation in Warm Inflation: Implications for the Primordial Power Spectrum
Ayush Sahu, Richa Arya, Sergio E. Jorás +1
Warm inflation is a well-motivated and generalized framework of inflation, describing a coupled inflaton-radiation bath. In this work, we investigate a warm inflation model with a…
