Description

Preheating is a crucial phase in the early universe where non-perturbative particle production occurs due to the oscillating backgroud field. While numerical methods have been widely used to study preheating dynamics, analytic approaches remain essential for gaining deeper theoretical insights and generalizing results across different models. In this talk, I will present the exact WKB analysis as a powerful analytical tool to investigate particle production during preheating.
