Reheating and turbulence

Abstract

We show that the ''turbulent'' particle spectra found in numerical simulations of the behavior of matter fields during reheating admit a simple interpretation in terms of hydrodynamic models of the reheating period. We predict a particle number spectrum $n_k\propto k^{-\alpha }$ with $\alpha \sim 2$ for $k\to 0.$
