Metric-Affine Gravity as an Effective Field Theory
A. Baldazzi, O. Melichev, R. Percacci
We discuss theories of gravity with independent metric (or frame field) and connection, from the point of view of effective field theory. We count the parity-even Lagrangian terms…
Relational observables in Asymptotically safe gravity
Alessio Baldazzi, Kevin Falls, Renata Ferrero
We introduce an approach to compute the renormalisation group flow of relational observables in quantum gravity which evolve from their microscopic expressions towards the full qua…
Essential Quantum Einstein Gravity
Alessio Baldazzi, Kevin Falls
The non-perturbative renormalisation of quantum gravity is investigated allowing for the metric to be reparameterised along the RG flow, such that only the essential couplings cons…
Essential renormalisation group
Alessio Baldazzi, Riccardo Ben Alì Zinati, Kevin Falls
We propose a novel scheme for the exact renormalisation group motivated by the desire of reducing the complexity of practical computations. The key idea is to specify renormalisati…
Limit of vanishing regulator in the functional renormalization group
Alessio Baldazzi, Roberto Percacci, Luca Zambelli
The non-perturbative functional renormalization group equation depends on the choice of a regulator function, whose main properties are a "coarse-graining scale" and an overall…
