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…
De Sitter quantum gravity within the covariant Lorentzian approach to asymptotic safety
Edoardo D'Angelo, Renata Ferrero, Markus B. Fröb
Recent technical and conceptual advancements in the asymptotic safety approach to quantum gravity have enabled studies of the UV completion of Lorentzian Einstein gravity, emphasiz…
Entropy-area law and temperature of de Sitter horizons from modular theory
Edoardo D'Angelo, Markus B. Fröb, Stefano Galanda +3
We derive an entropy-area law for the future horizon of an observer in diamonds inside the static patch of de Sitter spacetime, taking into account the backreaction of quantum matt…
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…
Asymptotic Safety in Lorentzian quantum gravity
Edoardo D'Angelo
We report on a recently introduced Functional Renormalization Group (RG) Equation, and we apply it to quantum gravity in Lorentzian spacetimes. While the RG flow is state-dependent…
Relative Entropy from Coherent States in Black Hole Thermodynamics and Cosmology
Edoardo D'Angelo
The aim of this work is to study the role of relative entropy in the thermodynamics of black holes and cosmological horizons. We adapt some recent results on the relative entropy o…
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…
Entropy for spherically symmetric, dynamical black holes from the relative entropy between coherent states of a scalar quantum field
Edoardo D'Angelo
The goal of this paper is to prove an area law for the entropy of dynamical, spherically symmetric black holes from the relative entropy between coherent states of the quantum matt…
