Causal Structure of a recent Loop Quantum Gravity Black Hole Collapse Model
Johannes Münch
The causal structure of the recent loop quantum gravity black hole collapse model [1] is analysed. As the spacetime is only approximately diffeomorphism invariant up to powers of $…
Effective Quantum Dust Collapse via Surface Matching
Johannes Münch
The fate of matter forming a black hole is still an open problem, although models of quantum gravity corrected black holes are available. In loop quantum gravity (LQG) models were…
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…
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…
