Oscillating Inflation with a non-minimally coupled scalar field

TL;DR

This paper explores an oscillating inflation model with a non-minimally coupled scalar field, confirming inflationary behavior through numerical analysis and highlighting the importance of small gravity-dilaton coupling for successful inflation.

Contribution

It extends the oscillating inflation model by incorporating non-minimal coupling and provides numerical evidence supporting inflationary dynamics.

Findings

Inflationary behavior confirmed numerically.

Successful inflation requires small gravity-dilaton coupling.

Density perturbations are obtained in the model.

Abstract

The oscillating inflation model recently proposed by Damour and Mukhanov is investigated with a non-minimal coupling. Numerical study confirms an inflationary behavior and the density perturbation is obtained. A successful inflation requires the gravity-dilaton coupling to be small.
