New higher-order transition in causal dynamical triangulations
J. Ambjorn, D. Coumbe, J. Gizbert-Studnicki +2
We reinvestigate the recently discovered bifurcation phase transition in Causal Dynamical Triangulations (CDT) and provide further evidence that it is a higher order transition. We…

Exploring the Phase Diagram of Lattice Quantum Gravity
Daniel Coumbe, Jack Laiho
We present evidence that a nonperturbative model of quantum gravity defined via Euclidean dynamical triangulations contains a region in parameter space with an extended 4-dimension…

Evidence for Asymptotic Safety from Lattice Quantum Gravity
J. Laiho, D. Coumbe
We calculate the spectral dimension for nonperturbative quantum gravity defined via Euclidean dynamical triangulations. We find that it runs from a value of ~3/2 at short distance…
