A hallmark of non-perturbative theories of quantum gravity is the absence of a fixed background geometry, and therefore the absence in a Planckian regime of any notion of length or…

The higher-order phase transition in toroidal CDT
Jan Ambjørn, Grzegorz Czelusta, Jakub Gizbert-Studnicki +3
We investigate the transition between the phases and observed in four-dimensional Causal Dynamical Triangulations (CDT). We find that the critical properties of CDT with…
