Quantum Gravity and Effective Topology
J. van der Duin, R. Loll, M. Schiffer +1
We introduce a new methodology to characterize properties of quantum spacetime in a strongly quantum-fluctuating regime, using tools from topological data analysis. Starting from a…

Curvature Correlators in Nonperturbative 2D Lorentzian Quantum Gravity
J. van der Duin, R. Loll
Correlation functions are ubiquitous tools in quantum field theory from both a fundamental and a practical point of view. However, up to now their use in theories of quantum gravit…

Scalar curvature for metric spaces: Defining curvature for Quantum Gravity without coordinates
Agustín Silva, Jesse van der Duin
Geometrical properties of spacetime are difficult to study in nonperturbative approaches to quantum gravity like Causal Dynamical Triangulations (CDT), where one uses simplicial ma…
