Asymptotic Safety within on-shell perturbation theory
Kevin Falls, Renata Ferrero
We investigate the renormalisation of Einstein gravity using a novel subtraction scheme in dimensional regularisation. The one-loop beta function for Newton's constant receives con…
Robustness of the derivative expansion in Asymptotic Safety
Alessio Baldazzi, Kevin Falls, Yannick Kluth +1
We analyse the renormalisation group flow of quantum gravity at sixth order in the derivative expansion within the background field approximation. Non-linear field redefinitions ar…
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…
Background independent exact renormalisation
Kevin Falls
A geometric formulation of Wilson's exact renormalisation group is presented based on a gauge invariant ultraviolet regularisation scheme without the introduction of a background f…
