Perturbative quantum gravity with the Immirzi parameter
Dario Benedetti, Simone Speziale
We study perturbative quantum gravity in the first-order tetrad formalism. The lowest order action corresponds to Einstein-Cartan plus a parity-odd term, and is known in the litera…
The Universal RG Machine
Dario Benedetti, Kai Groh, Pedro F. Machado +1
Functional Renormalization Group Equations constitute a powerful tool to encode the perturbative and non-perturbative properties of a physical system. We present an algorithm to sy…
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…
Imposing causality on a matrix model
Dario Benedetti, Joe Henson
We introduce a new matrix model that describes Causal Dynamical Triangulations (CDT) in two dimensions. In order to do so, we introduce a new, simpler definition of 2D CDT and show…
Fractal properties of quantum spacetime
Dario Benedetti
We show that in general a spacetime having a quantum group symmetry has also a scale dependent fractal dimension which deviates from its classical value at short scales, a phenomen…
