Renormalisation of out-of-equilibrium quantum fields
Szabolcs Borsanyi, Urko Reinosa
We consider the initial value problem and its renormalisation in the framework of the two-particle-irreducible (2PI) effective action. We argue that in the case of appropriately ch…

Renormalised nonequilibrium quantum field theory: scalar fields
Szabolcs Borsanyi, Urko Reinosa
We discuss the renormalisation of the initial value problem in quantum field theory using the two-particle irreducible (2PI) effective action formalism. The nonequilibrium dynamics…
