Spectral geometry as a probe of quantum spacetime
Dario Benedetti, Joe Henson
Employing standard results from spectral geometry, we provide strong evidence that in the classical limit the ground state of three-dimensional causal dynamical triangulations is d…
Four-derivative interactions in asymptotically safe gravity
Dario Benedetti, Pedro F. Machado, Frank Saueressig
We summarize recent progress in understanding the role of higher-derivative terms in the asymptotic safety scenario of gravity. Extending previous computations based on the functio…
Taming perturbative divergences in asymptotically safe gravity
Dario Benedetti, Pedro F. Machado, Frank Saueressig
We use functional renormalization group methods to study gravity minimally coupled to a free scalar field. This setup provides the prototype of a gravitational theory which is pert…
Asymptotic safety in higher-derivative gravity
Dario Benedetti, Pedro F. Machado, Frank Saueressig
We study the non-perturbative renormalization group flow of higher-derivative gravity employing functional renormalization group techniques. The non-perturbative contributions to t…
