The phase structure and effective action of 3D CDT at higher spatial genus
Joren Brunekreef, Dániel Németh
We perform a detailed investigation of the phase structure and the semiclassical effective action of (2+1)-dimensional Causal Dynamical Triangulations (CDT) quantum gravity using c…

On the Nature of Spatial Universes in 3D Lorentzian Quantum Gravity
J. Brunekreef, R. Loll
Three-dimensional Lorentzian quantum gravity, expressed as the continuum limit of a nonperturbative sum over spacetimes, is tantalizingly close to being amenable to analytical meth…
