Ward Identities for the 2PI effective action in QED
U. Reinosa, J. Serreau
We study the issue of symmetries and associated Ward-like identities in the context of two-particle-irreducible (2PI) functional techniques for abelian gauge theories. In the 2PI f…

2PI renormalized effective action for gauge theories
U. Reinosa
We show how to perform renormalization in the framework of the 2PI effective action for abelian gauge theories. In addition to the usual renormalization conditions one needs to inc…

Renormalized Finite Temperature phi^4 theory from the 2PI Effective Action
A. Arrizabalaga, U. Reinosa
We present an analytical and numerical study of scalar phi^4 theory at finite temperature with a renormalized 2-loop truncation of the 2PI effective action.
