On realtime evolution cosmology
Abstract
Realtime evolution plays an important role to understand the dynamics of the early universe. It would be of importance to investigate typical time dependent processes like particle production, reheating, the creation and evolution of fluctuations, etc. In this paper, the oneloop renormalized coupled Einstein field equations are derived for a scalar field with lambda(Phi exp 4) interaction in a classical curved spacetime of FriedmannRobertsonWalker type. These equations can be used to calculate quantum corrections for the dynamics in the early universe.
