Massive spin 3 and Metric-Affine Gravity
Roberto Percacci, Ergin Sezgin
Symmetric Metric-Affine Gravity is a theory of gravity with an independent non-metric connection, and zero torsion. It can be thought of as ordinary metric gravity coupled to a ran…
Quantum fields and the cosmological constant
Renata Ferrero, Vincenzo Naso, Roberto Percacci
It has been shown that if one solves self-consistently the semiclassical Einstein equations in the presence of a quantum scalar field, with a cutoff on the number of modes, spaceti…
The Starobinsky model of inflation and Renormalizability
Roberto Percacci, Gian Paolo Vacca
The Starobinsky model was born in a cosmological scenario where conformally coupled matter quantum field fluctuations on the vacuum drive a non trivial semiclassical energy momentu…
Quantum Gravity, Hydrodynamics and Emergent Cosmology: A Collection of Perspectives
Jibril Ben Achour, Dario Benedetti, Martin Bojowald +17
This collection of perspective pieces captures recent advancements and reflections from a dynamic research community dedicated to bridging quantum gravity, hydrodynamics, and emerg…
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…
Renormalization and running in the 2D model
Diego Buccio, John F. Donoghue, Gabriel Menezes +1
We calculate the scattering amplitude in the two dimensional model in a regularization scheme independent way. When using cutoff regularization, a new Feynman rule from the…
