Quantum Schwarzschild-(A)dS black holes: unitarity and singularity resolution

Journal of High Energy Physics
We consider the canonical quantisation of spherically symmetric spacetimes within unimodular gravity, leaving sign choices in the metric general enough to include both the interior and exterior Schwarzschild-(Anti-)de Sitter spacetime.

Time evolution in canonical quantum gravity is trivial

Annals of Physics
The Wheeler-DeWitt (WdW) equation does not describe any explicit time evolution of the wave function, and somehow related to this issue, there is no natural way of defining an invariant inner product that provides a viable probability interpretation.
