RG flows of Quantum Einstein Gravity in the linear-geometric approximation
Maximilian Demmel, Frank Saueressig, Omar Zanusso
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…
Spectral dimensions from the spectral action
Natalia Alkofer, Frank Saueressig, Omar Zanusso
The generalised spectral dimension provides a powerful tool for comparing different approaches to quantum gravity. In this work, we apply this formalism to the classica…
Effective models of membranes from symmetry breaking
O. Zanusso
We show how to obtain all the models of the continuous description of membranes by constructing the appropriate non-linear realizations of the Euclidean symmetries of the embedding…
RG flows of Quantum Einstein Gravity on maximally symmetric spaces
Maximilian Demmel, Frank Saueressig, Omar Zanusso
We use the Wetterich-equation to study the renormalization group flow of -gravity in a three-dimensional, conformally reduced setting. Building on the exact heat kernel for m…
