A multicritical Landau-Potts field theory
Alessandro Codello, Mahmoud Safari, Gian Paolo Vacca +1
We investigate a perturbatively renormalizable invariant model with scalar field components below the upper critical dimension . Our results hint…
Crossover exponents, fractal dimensions and logarithms in Landau-Potts field theories
Mahmoud Safari, Gian Paolo Vacca, Omar Zanusso
We compute the crossover exponents of all quadratic and cubic deformations of critical field theories with permutation symmetry in (Landau-Potts field theories) and $…
On critical models with scalars in
Alessandro Codello, Mahmoud Safari, Gian Paolo Vacca +1
We adopt a combination of analytical and numerical methods to study the renormalization group flow of the most general field theory with quartic interaction in with a…
Critical reflections on asymptotically safe gravity
Alfio Bonanno, Astrid Eichhorn, Holger Gies +5
Asymptotic safety is a theoretical proposal for the ultraviolet completion of quantum field theories, in particular for quantum gravity. Significant progress on this program has le…
Wilsonian Renormalization Group In The Functional Nonperturbative Approach
Gian Paolo Vacca
We consider a functional relation between a given Wilsonian RG flow, which has to be related to a specific coarse-graining procedure, and an infinite family of (UV cutoff) scale de…
On Exact Proper Time Wilsonian RG Flows
A. Bonanno, S. Lippoldt, R. Percacci +1
We discuss the possibility to define exact RG equations for a UV regulated Wilsonian action based on a proper time (PT) regulator function. We start from a functional mapping which…
