Cyclic Kruskal Universe: a quantum-corrected Schwarzschild black hole in unitary unimodular gravity
Steffen Gielen, Sofie Ried
We analyse the physical properties of an analytical, nonsingular quantum-corrected black hole solution recently derived in a minisuperspace model for unimodular gravity under the a…

Singularity Resolution of Quantum Black Holes in (A)dS
Sofie Ried
The singularities present at the centre of black holes signal a break down of the classical theory. In this paper, we demonstrate a resolution of the Schwarzschild-(Anti-)de Sitter…

Quantum Schwarzschild-(A)dS Black Holes: Unitarity and Singularity Resolution
Steffen Gielen, Sofie Ried
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…
