Analysis
This paper investigates a mechanism for reheating the universe after inflation, focusing on a Higgs inflationary scenario. It explores how gravitational effects alone can create particles and initiate the standard thermal history, particularly in models without direct inflaton couplings. The study's significance lies in providing a potential solution to the reheating problem in minimal inflationary models, demonstrating that gravity can play a crucial role in the early universe's evolution.
Key Takeaways
- •Addresses the reheating problem in inflationary models without direct inflaton couplings.
- •Focuses on a Higgs inflationary scenario with non-minimal curvature coupling.
- •Demonstrates that gravitational effects can drive particle production.
- •Proposes a curvature-driven production mechanism as an efficient reheating route.

“The rapid, oscillatory evolution of the curvature scalar after inflaton acts as a time dependent gravitational pump, creating scalar spectator particles even in the absence of explicit interactions.”
