Non-Gaussianity from Instant and Tachyonic Preheating
Kari Enqvist, Asko Jokinen, Anupam Mazumdar +2
We study non-Gaussianity in two distinct models of preheating: instant and tachyonic. In instant preheating non-Gaussianity is sourced by the local terms generated through the coup…

Non-Gaussianity from Preheating
Kari Enqvist, Asko Jokinen, Anupam Mazumdar +2
We consider a two-field model for inflation where the second order metric perturbations can be amplified by a parametric resonance during preheating. We demonstrate that there can…
