Renormalization group bounds on Araki relative entropy
Edoardo D'Angelo
This paper derives a multiscale Bakry-Émery criterion for an upper bound on the Araki relative entropy of perturbations of an equilibrium state in relativistic QFT. Using stochasti…
Local solutions of RG flow equations from the Nash-Moser theorem
Edoardo D'Angelo, Nicola Pinamonti
We prove local existence of solutions of a functional Renormalisation Group equation for the effective action of an interacting quantum field theory, when a suitable Local Potentia…
A Lorentzian renormalisation group equation for gauge theories
Edoardo D'Angelo, Kasia Rejzner
In a recent paper, with Drago and Pinamonti we have introduced a Wetterich-type flow equation for scalar fields on Lorentzian manifolds, using the algebraic approach to perturbativ…
An algebraic QFT approach to the Wetterich equation on Lorentzian manifolds
Edoardo D'Angelo, Nicolò Drago, Nicola Pinamonti +1
We discuss the scaling of the effective action for the interacting scalar quantum field theory on generic spacetimes with Lorentzian signature and in a generic state (including vac…
