2PI functional techniques for abelian gauge theories
U. Reinosa, J. Serreau
We summarize our recent work [1-3] concerning the formulation of two-particle-irreducible (2PI) functional techniques for abelian gauge field theories.
The pressure of QED from the two-loop 2PI effective action
Szabolcs Borsanyi, Urko Reinosa
We compute the pressure of hot quantum electrodynamics from the two-loop truncation of the 2PI effective action. Since the 2PI resummation guarantees gauge-fixing independence only…
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.
Nonperturbative renormalization of Phi-derivable approximations in theories with fermions
U. Reinosa
We show how to renormalize Phi-derivable approximations in a theory with a fermionic field coupled to a self-interacting scalar field through a Yukawa interaction. The nonperturbat…
The entropy of hot QCD at large N_f: Successfully testing weak coupling techniques
Jean-Paul Blaizot, Andreas Ipp, Anton Rebhan +1
It has been known for some time that the entropy of hot QCD is well reproduced by weak coupling techniques. These do not identify with perturbation theory, known to have poor conve…
