Asymptotic Safety in Generalized Proca Theories
Lavinia Heisenberg, Alessia Platania, Sara Rufrano Aliberti
Generalized Proca Theories are the most general higher-derivative extensions of a massive vector field that retain second-order equations of motion. They are phenomenologically int…
Asymptotic safety, quantum gravity, and the swampland: a conceptual assessment
Ivano Basile, Benjamin Knorr, Alessia Platania +1
We provide a conceptual assessment of some aspects of fundamental quantum field theories of gravity in light of foundational aspects of the swampland program. On the one hand, asym…
Visions in Quantum Gravity
Luca Buoninfante, Benjamin Knorr, K. Sravan Kumar +36
To deepen our understanding of Quantum Gravity and its connections with black holes and cosmology, building a common language and exchanging ideas across different approaches is cr…
Lectures in Quantum Gravity
Ivano Basile, Luca Buoninfante, Francesco Di Filippo +3
Formulating a quantum theory of gravity lies at the heart of fundamental theoretical physics. This collection of lecture notes encompasses a selection of topics that were covered i…
Charting GLOBs in Asymptotically Safe Gravity
Francesco Del Porro, Jonas Pfeiffer, Alessia Platania +1
Computing the gravitational effective action provides a direct route to charting the landscape of admissible black hole spacetimes and their alternatives, which we will collectivel…
Impact of quantum gravity on the UV sensitivity of extremal black holes
Francesco Del Porro, Francesco Ferrarin, Alessia Platania
Recent work has revealed that extremal Kerr black holes may exhibit a sensitivity to higher-derivative corrections to Einstein's equations, displaying singularities in the tidal fo…
