Reheating and turbulence

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∝k -α with α∼2 for k→0. © 2002 The...

Sumario: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∝k -α with α∼2 for k→0. © 2002 The American Physical Society.
