A second-order phase transition in CDT
arXiv:1108.3932 · doi:10.1103/PhysRevLett.107.211303
Abstract
Causal Dynamical Triangulations (CDT) are a concrete attempt to define a nonperturbative path integral for quantum gravity. We present strong evidence that the lattice theory has a second-order phase transition line, which can potentially be used to define a continuum limit in the conventional sense of nongravitational lattice theories.
