A c=1 phase transition in two-dimensional CDT/Horava-Lifshitz gravity?
Abstract
We study matter with central charge coupled to two-dimensional (2d) quantum gravity, here represented as causal dynamical triangulations (CDT). 2d CDT is known to provide a regularization of (Euclidean) 2d Ho\v{r}ava-Lifshitz quantum gravity. The matter fields are massive Gaussian fields, where the mass is used to monitor the central charge . Decreasing the mass we observe a higher order phase transition between an effective theory and a theory where . In this sense the situation is somewhat similar to that observed for "standard" dynamical triangulations (DT) which provide a regularization of 2d quantum Liouville gravity. However, the geometric phase observed for in CDT is very different from the corresponding phase observed for DT.
