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…
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…
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…
Towards the determination of the dimension of the critical surface in asymptotically safe gravity
Kevin Falls, Nobuyoshi Ohta, Roberto Percacci
We compute the beta functions of Higher Derivative Gravity within the Functional Renormalization Group approach, going beyond previously studied approximations. We find that the pr…
Frame (In)equivalence in Quantum Field Theory and Cosmology
Kevin Falls, Mario Herrero-Valea
We revisit the question of frame equivalence in Quantum Field Theory in the presence of gravity, a situation of relevance for theories aiming to describe the early Universe dynamic…
