Inflation and nonequilibrium renormalization group
Juan Zanella, Esteban Calzetta
We study de spectrum of primordial fluctuations and the scale dependence of the inflaton spectral index due to self-interactions of the field. We compute the spectrum of fluctuatio…

Renormalization group study of damping in nonequilibrium field theory
J. Zanella, E. Calzetta
In this paper we shall study whether dissipation in a may be described, in the long wavelength, low frequency limit, with a simple Ohmic term , as it is usually do…

A nonequilibrium renormalization group approach to turbulent reheating
Juan Zanella, Esteban Calzetta
We use nonequilibrium renormalization group (RG) techniques to analyze the thermalization process in quantum field theory, and by extension reheating after inflation. Even if at a…
