Further evidence for asymptotic safety of quantum gravity

K Falls, D Litim, K Nikolakopoulos, C Rahmede - Physical Review D, 2016 - APS
The asymptotic safety conjecture is examined for quantum gravity in four dimensions. Using
the renormalization group, we find evidence for an interacting UV fixed point for polynomial …

Aspects of asymptotic safety for quantum gravity

KG Falls, DF Litim, J Schröder - Physical Review D, 2019 - APS
We study fixed points of quantum gravity with renormalization group methods and a
procedure to remove convergence-limiting poles from the flow. The setup is tested within the …

Asymptotic safety of gravity with matter

N Christiansen, DF Litim, JM Pawlowski, M Reichert - Physical Review D, 2018 - APS
We study the asymptotic safety conjecture for quantum gravity in the presence of matter
fields. A general line of reasoning is put forward explaining why gravitons dominate the high …

Gravitational two-loop counterterm is asymptotically safe

H Gies, B Knorr, S Lippoldt, F Saueressig - Physical Review Letters, 2016 - APS
Weinberg's asymptotic safety scenario provides an elegant mechanism to construct a
quantum theory of gravity within the framework of quantum field theory based on a non …

Asymptotic safety of quantum gravity beyond Ricci scalars

K Falls, CR King, DF Litim, K Nikolakopoulos… - Physical Review D, 2018 - APS
We investigate the asymptotic safety conjecture for quantum gravity including curvature
invariants beyond Ricci scalars. Our strategy is put to work for families of gravitational …

Dynamical renormalization of black-hole spacetimes

A Platania - The European Physical Journal C, 2019 - Springer
We construct a black-hole spacetime which includes the running of the gravitational
coupling in a self-consistent way. Starting from a classical Schwarzschild black hole, the …

Towards apparent convergence in asymptotically safe quantum gravity

T Denz, JM Pawlowski, M Reichert - The European Physical Journal C, 2018 - Springer
The asymptotic safety scenario in gravity is accessed within the systematic vertex expansion
scheme for functional renormalisation group flows put forward in Christiansen et al.(Phys …

Local quantum gravity

N Christiansen, B Knorr, J Meibohm, JM Pawlowski… - Physical Review D, 2015 - APS
We investigate the ultraviolet behavior of quantum gravity within a functional renormalization
group approach. The present setup includes the full ghost and graviton propagators and, for …
