Graceful Exit to Radiation Domination in the Starobinsky Model: A Dynamical Realization
Bhargabi Saha, Malay K. Nandy
The Starobinsky model provides a successful realization of inflation and serves as a benchmark for alternative inflationary models. Motivated by its observational success, we inves…

Dynamical Evolution and Graceful Exit in Quartic Warm Inflation
Bhargabi Saha, Malay K. Nandy
In this study, we investigate the full nonlinear dynamics of warm inflation driven by the quartic inflaton potential, avoiding any simplifying approximations. The thermal backreact…

The -Attractor E-Model in Warm Inflation: Observational Viability from Planck 2018
Bhargabi Saha, Malay K. Nandy
We explore the inflationary evolution and observational viability of the -attractor E-model in the framework of warm inflation, focusing on both weak and strong dissipative regi…
