报告内容：

Parametric resonance is a crucial mechanism for particle production during the reheating phase of the early universe. During the inflationary period before reheating, we effectively generated primordial black holes through model construction utilizing parametric resonance. Additionally, we induced gravitational waves using the parametric resonance method while ensuring that scalar perturbations comply with observational constraints, thereby observationally beating the Lyth bound. This seminar will provide a detailed introduction to the application of parametric resonance in the early universe and its profound implications for cosmological models.
