Curvature dependence of quantum gravity
Nicolai Christiansen, Kevin Falls, Jan M. Pawlowski +1
We investigate the phase diagram of quantum gravity with a vertex expansion about constantly-curved backgrounds. The graviton two- and three-point function are evaluated with a spe…
One force to rule them all: asymptotic safety of gravity with matter
Nicolai Christiansen, Daniel F. Litim, Jan M. Pawlowski +1
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 hig…
Is scale-invariance in gauge-Yukawa systems compatible with the graviton?
Nicolai Christiansen, Astrid Eichhorn, Aaron Held
We explore whether perturbative interacting fixed points in matter systems can persist under the impact of quantum gravity. We first focus on semi-simple gauge theories and show th…
An asymptotically safe solution to the U(1) triviality problem
Nicolai Christiansen, Astrid Eichhorn
We explore whether quantum gravity effects within the asymptotic safety paradigm can provide a predictive ultraviolet completion for Abelian gauge theories. We evaluate the effect…
