Bilocal flows and universality with field-dependent regulators
Alfio M. Bonanno, Renata Ferrero
Many functional renormalization group flows employ a regulator that depends on the fields, as in proper-time and spectrally adjusted flows and in background-independent formulation…
Fifth-Force Constraints from UV-Complete Scalar-Tensor Gravity
Alfio M. Bonanno, Emiliano M. Glaviano
We study an scalar multiplet nonminimally coupled to gravity and follow its renormalization-group (RG) flow in the vicinity of an interacting, nonperturbatively UV-complete…
Coarse graining from within: Wilson-Fisher universality on
Alfio M. Bonanno, Renata Ferrero, Giovanni Oglialoro
Wilsonian renormalization is usually formulated in momentum space, but on curved backgrounds momentum shells have no invariant meaning. We replace them by an intrinsic spectral cut…
Scaling Solutions of Matter Form Factors in Asymptotically Safe Quantum Gravity
Alfio M. Bonanno, Diego Buccio, Emiliano M. Glaviano +1
We investigate the renormalization group flow of a gravity--matter system in which a scalar field is minimally coupled to Einstein gravity and its kinetic term is given by a scale-…
Effective potentials for de Sitter and anti de Sitter quantum fields
Alfio Bonanno, Sergio Luigi Cacciatori, Ugo Moschella
We derive a systematic treatment of one-loop effective potentials for interacting scalar fields in curved spacetimes, providing a general formula valid in arbitrary geometries and…
Gauge and parametrization dependence of Quantum Einstein Gravity within the Proper Time flow
Alfio Bonanno, Giovanni Oglialoro, Dario Zappalà
Proper time functional flow equations have garnered significant attention in recent years, as they are particularly suitable in analyzing non-perturbative contexts. By resorting to…
Proper-time flow equation and non-local truncations in quantum gravity
E. M. Glaviano, A. Bonanno
We study the flow of the non-local truncation in quantum gravity and we focus in particular on the Polyakov effective action for a non-minimally coupled scalar field on a two dimen…
Spontaneous breaking of diffeomorphism invariance in conformally reduced quantum gravity
G. Giacometti, A. Bonanno, S. Plumari +1
We study the spontaneous breaking of diffeomorphism invariance using the proper-time non-perturbative flow equation in quantum gravity. In particular, we analyze the structure of t…
Towards an accurate determination of the critical exponents with the Renormalization Group flow equations
A. Bonanno, D. Zappalà
The determination of the critical exponents by means of the Exact Renormalizion Group approach is still a topic of debate. The general flow equation is by construction scheme indep…
