Parametric Decay of the Curvaton
K. Enqvist, S. Nurmi, G. I. Rigopoulos
We argue that the curvaton decay takes place most naturally by way of a broad parametric resonance. The mechanism is analogous to resonant inflaton decay but does not require any t…

On the divergences of inflationary superhorizon perturbations
K. Enqvist, S. Nurmi, D. Podolsky +1
We discuss the infrared divergences that appear to plague cosmological perturbation theory. We show that within the stochastic framework they are regulated by eternal inflation so…

Non-Gaussianity in Curvaton Models with Nearly Quadratic Potential
Kari Enqvist, Sami Nurmi
We consider curvaton models with potentials that depart slightly from the quadratic form. We show that although such a small departure does not modify significantly the Gaussian pa…
