Description

Gravitational fluctuations can be affected by preheating after inflation, even on scales larger than the Hubble radius, without violating causality. We discuss linear and non-linear aspects in the evolution of gravitational fluctuations during this stage and its implications for the final spectrum of curvature perturbations.
