Renormalization and gauge symmetry for 2PI effective actions
Urko Reinosa
We explore a method to recover symmetry identities in the 2PI formalism. It is based on non-perturbative approximations to the 1PI effective action. We discuss renormalization ques…

Isolating vacuum amplitudes in quantum field calculations at finite temperature
Jean-Paul Blaizot, Urko Reinosa
In calculating Feynman diagrams at finite temperature, it is sometimes convenient to isolate subdiagrams which do not depend explicitly on the temperature. We show that, in the ima…
