Chaos and Preheating
Sergio E. Jor\'as, Victor H. C\'ardenas
TL;DR
This paper explores the connection between chaos and parametric resonance in classical and semiclassical systems, applying these ideas to a toy model of preheating after cosmic inflation.
Contribution
It demonstrates a relationship between chaos and parametric resonance in both classical and semiclassical contexts, with applications to inflationary preheating models.
Findings
Evidence of chaos-resonance connection in classical systems
Semiclassical analysis of particle creation during preheating
Implications for inflationary cosmology
Abstract
We show evidence for a relationship between chaos and parametric resonance both in a classical system and in the semiclassical process of particle creation. We apply our considerations in a toy model for preheating after inflation.
