Evolution of coupled scalar perturbations through smooth reheating. I. Dissipative regime
M. Laine, S. Procacci, A. Rogelj
If the inflaton is a heavy scalar field, it may equilibrate slower than some other degrees of freedom, e.g. non-Abelian gauge bosons. In this case, perturbations in the inflaton fi…

Smooth reheating and dark matter via non-Abelian gauge theory
Simone Biondini, Helena Kolesova, Simona Procacci
We demonstrate how a dark sector can provide a crucial link between a vacuum-dominated early universe and the later radiation-dominated epoch. As an example, we consider a feeble a…
