Renormalization of nonequilibrium dynamics at large N and finite temperature
Juergen Baacke, Katrin Heitmann, Carsten Patzold
We generalize a previously proposed renormalization and computation scheme for nonequilibrium dynamics to include finite temperature and one-loop selfconsistency as arising in the…
On the choice of initial states in nonequilibrium dynamics
Juergen Baacke, Katrin Heitmann, Carsten Patzold
Imposing initial conditions to nonequilibrium systems at some time t_0 leads, in renormalized quantum field theory, to the appearance of singularities in the variable t-t_0 in rele…
Renormalization of nonequilibrium dynamics in FRW cosmology
Jurgen Baacke, Katrin Heitmann, Carsten Patzold
We derive the renormalized nonequilibrium equations of motion for a scalar field and its quantum back reaction in a conformally flat Friedmann-Robertson-Walker universe. We use a f…
