Description:
Author(s): J. Berges, D. Gelfand, and D. Sexty We study the real-time dynamics of fermions coupled to scalar fields in a linear sigma model, which is often employed in the context of preheating after inflation or as a low-energy effective model for quantum chromodynamics. We find a dramatic amplification of fermion production in the presence of ... [Phys. Rev. D 89, 025001] Published Mon Jan 06, 2014
