Aspects of dynamical dimensional reduction in multigraph ensembles of CDT
Georgios Giasemidis, John F. Wheater, Stefan Zohren
We study the continuum limit of a "radially reduced" approximation of Causal Dynamical Triangulations (CDT), so-called multigraph ensembles, and explain why they serve as realistic…
Spectral dimension flow on continuum random multigraph
Georgios Giasemidis, John F. Wheater, Stefan Zohren
We review a recently introduced effective graph approximation of causal dynamical triangulations (CDT), the multigraph ensemble. We argue that it is well suited for analytical comp…
Continuum Random Combs and Scale Dependent Spectral Dimension
Max R Atkin, Georgios Giasemidis, John F Wheater
Numerical computations have suggested that in causal dynamical triangulation models of quantum gravity the effective dimension of spacetime in the UV is lower than in the IR. In th…
