Exact Renormalization Group with Fermions
Jordi Comellas
The development of the Exact Renormalization Group for fermionic theories is presented, together with its application to the chiral Gross-Neveu model. We focus on the reliability o…

Approximate solutions in scalar and fermionic theories within the exact renormalization group approach
Jordi Comellas, Yuri Kubyshin, Enrique Moreno
We give a review of the exact renormalization group (ERG) approach and illustrate its applications in scalar and fermionic theories. The derivative expansion and approximations bas…

Wilsonian vs. 1PI renormalization group flow irreversibility
Jordi Comellas, Jose I. Latorre
We present a line of reasoning based on the analysis of scale variations of the Wilsonian partition function and the trace of the stress tensor in a curved manifold which results i…
