Recent results in CDT quantum gravity

Understand

We review some recent results from the causal dynamical triangulation (CDT) approach to quantum gravity.

• We review recent observations of dimensional reduction at a number of previously undetermined points in the parameter space of CDT, and discuss their possible relevance to the asymptotic safety scenario.
• We also present an updated phase diagram of CDT, discussing properties of a newly discovered phase and its possible relation to a signature change of the metric.
