A fascinating and deep question about nature is what one would see if one could probe space and time at smaller and smaller distances. Already the 19th-century founders of modern g…

Taming the cosmological constant in 2D causal quantum gravity with topology change
R. Loll, W. Westra, S. Zohren
As shown in previous work, there is a well-defined nonperturbative gravitational path integral including an explicit sum over topologies in the setting of Causal Dynamical Triangul…

Counting a black hole in Lorentzian product triangulations
B. Dittrich, R. Loll
We take a step toward a nonperturbative gravitational path integral for black-hole geometries by deriving an expression for the expansion rate of null geodesic congruences in the a…
