Mass and Horizon Dirac Observables in Effective Models of Quantum Black-to-White Hole Transition
Norbert Bodendorfer, Fabio M. Mele, Johannes Münch
In the past years, black holes and the fate of their singularity have been heavily studied within loop quantum gravity. Effective spacetime descriptions incorporating quantum geome…
Covariant Momentum Map Thermodynamics for Parametrized Field Theories
Goffredo Chirco, Marco Laudato, Fabio M. Mele
A general-covariant statistical framework capable of describing classical fluctuations of the gravitational field is a thorny open problem in theoretical physics, yet ultimately ne…
Effective Quantum Extended Spacetime of Polymer Schwarzschild Black Hole
Norbert Bodendorfer, Fabio M. Mele, Johannes Münch
The physical interpretation and eventual fate of gravitational singularities in a theory surpassing classical general relativity are puzzling questions that have generated a great…
A note on the Hamiltonian as a polymerisation parameter
Norbert Bodendorfer, Fabio M. Mele, Johannes Münch
In effective models of loop quantum gravity, the onset of quantum effects is controlled by a so-called polymerisation scale. It is sometimes necessary to make this scale phase spac…
Is limiting curvature mimetic gravity an effective polymer quantum gravity?
Norbert Bodendorfer, Fabio M. Mele, Johannes Münch
A recently proposed version of mimetic gravity incorporates a limiting curvature into general relativity by means of a specific potential depending on the d'Alembertian of the scal…
Holographic Signatures of Resolved Cosmological Singularities II: Numerical Investigations
Norbert Bodendorfer, Fabio M. Mele, Johannes Münch
A common strategy to investigate the fate of gravitational singularities in asymptotically AdS spacetimes is to translate the question from the gravitational side to a dual field t…
