Cosmic Inflation: Background dynamics, Quantum fluctuations and Reheating
arXiv:2403.10606
Abstract
These lecture notes provide a pedagogical introduction to some aspects of the inflationary cosmology, including the background scalar field dynamics, generation of primordial seed perturbations via quantum fluctuations during inflation, and the process of reheating after inflation in the single-field inflationary paradigm.
