Causal Dynamical Triangulations: New Lattice Theory of Quantum Gravity
J. Ambjørn, R. Loll
Causal Dynamical Triangulations (CDT) is a methodology to define and compute the gravitational path integral, whose aim is a fully fledged nonperturbative quantum field theory of g…
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…
Exploring Quantum Spacetime with Topological Data Analysis
J. van der Duin, R. Loll, M. Schiffer +1
In a novel application of the tools of topological data analysis (TDA) to nonperturbative quantum gravity, we introduce a new class of observables that allows us to assess whether…
What is the Curvature of 2D Euclidean Quantum Gravity?
R. Loll, T. Niestadt
We re-examine the nonperturbative curvature properties of two-dimensional Euclidean quantum gravity, obtained as the scaling limit of a path integral over dynamical triangulations…
Nonperturbative quantum gravity unlocked through computation
R. Loll
Being able to perform explicit computations in a nonperturbative, Planckian regime is key to understanding quantum gravity as a fundamental theory of gravity and spacetime. Rather…
