Dissipation of oscillating scalar backgrounds in an FLRW universe

Abstract We study the dissipation of oscillating scalar backgrounds in a spatially flat Friedmann-Lemaître-Robertson-Walker universe using non-equilibrium quantum field theory. To be concrete, a Z 2-symmetric two-scalar model with quartic interactions is used. For quasi-harmonic oscillations, we ado...
