Abstract

We extend the recent work by Finelli and Brandenberger and study the possibilities of parametric amplification of the gravitational perturbation in models of a massless and a massive inflatons with self-coupled interactions. Our results show that there is no additional growth of the super-horizon modes during reheating beyond the usual predictions.
