Zooming in on fermions and quantum gravity
Astrid Eichhorn, Stefan Lippoldt, Marc Schiffer
We zoom in on the microscopic dynamics for fermions and quantum gravity within the asymptotic-safety paradigm. A key finding of our study is the unavoidable presence of a nonminima…

How perturbative is quantum gravity?
Astrid Eichhorn, Stefan Lippoldt, Jan M. Pawlowski +2
We explore asymptotic safety of gravity-matter systems, discovering indications for a near-perturbative nature of these systems in the ultraviolet. Our results are based on the dyn…

Renormalized Functional Renormalization Group
Stefan Lippoldt
We construct a new version of the effective average action together with its flow equation. The construction entails in particular the consistency of fluctuation field and backgrou…
