Black holes are probably among the most fascinating objects populating our universe. Their
characteristic features found within general relativity, encompassing space–time …

A short introduction is given on the functional renormalization group method, putting
emphasis on its nonperturbative aspects. The method enables to find nontrivial fixed points …

We investigate the compatibility of minimally coupled scalar, fermion and gauge fields with
asymptotically safe quantum gravity, using nonperturbative functional renormalization group …

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 …

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 …

We write new functional renormalization group equations for a scalar nonminimally coupled
to gravity. Thanks to the choice of the parametrization and of the gauge fixing they are …

The phase diagram of four-dimensional Einstein–Hilbert gravity is studied using Wilsonʼs
renormalization group. Smooth trajectories connecting the ultraviolet fixed point at short …

We study four-dimensional quantum gravity using nonperturbative renormalization group
methods. We solve the corresponding equations for the fully momentum-dependent …

In the context of our work on multi-fold universes, and the emergence of gravity from
entanglement, we argued that quantum gravity is asymptotically safe in multi-fold universe …

We construct a novel Wetterich-type functional renormalization group equation for gravity
which encodes the gravitational degrees of freedom in terms of gauge-invariant fluctuation …
