Field space parametrization in quantum gravity and the identification of a unitary conformal field theory at the heart of 2D Asymptotic Safety
Andreas Nink
In this thesis we investigate various fundamental aspects of asymptotically safe quantum gravity, in particular the compatibility of Asymptotic Safety with the requirements for bac…
The unitary conformal field theory behind 2D Asymptotic Safety
Andreas Nink, Martin Reuter
Being interested in the compatibility of Asymptotic Safety with Hilbert space positivity (unitarity), we consider a local truncation of the functional RG flow which describes quant…
Connections and geodesics in the space of metrics
Maximilian Demmel, Andreas Nink
We argue that the exponential relation is the most natural metric parametrization since it describes geodesics that follow from th…
Field Parametrization Dependence in Asymptotically Safe Quantum Gravity
Andreas Nink
Motivated by conformal field theory studies we investigate Quantum Einstein Gravity with a new field parametrization where the dynamical metric is basically given by the exponentia…
On quantum gravity, Asymptotic Safety, and paramagnetic dominance
Andreas Nink, Martin Reuter
We discuss the conceptual ideas underlying the Asymptotic Safety approach to the nonperturbative renormalization of gravity. By now numerous functional renormalization group studie…
On the physical mechanism underlying Asymptotic Safety
Andreas Nink, Martin Reuter
We identify a simple physical mechanism which is at the heart of Asymptotic Safety in Quantum Einstein Gravity (QEG) according to all available effective average action-based inves…
