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…

Some simple theories of gravity with propagating torsion
Yusuke Mikura, Vincenzo Naso, Roberto Percacci
We consider antisymmetric Metric-Affine Theories of Gravity with a Lagrangian containing the most general terms up to dimension four and search for theories that are ghost- and tac…
