Unimodular boundary time for Regge calculus
Steffen Gielen, Sofie Ried
Henneaux-Teitelboim gravity is a diffeomorphism-invariant formulation of unimodular gravity that is locally equivalent to general relativity but includes an extra boundary variable…

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…
