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…
Stochastic quantization and the role of time in quantum gravity
J. Ambjorn, R. Loll, W. Westra +1
We show that the noncritical string field theory developed from two-dimensional quantum gravity in the framework of causal dynamical triangulations can be viewed as arising through…
A new continuum limit of matrix models
J. Ambjorn, R. Loll, Y. Watabiki +2
We define a new scaling limit of matrix models which can be related to the method of causal dynamical triangulations (CDT) used when investigating two-dimensional quantum gravity.…
A Matrix Model for 2D Quantum Gravity defined by Causal Dynamical Triangulations
J. Ambjorn, R. Loll, Y. Watabiki +2
A novel continuum theory of two-dimensional quantum gravity, based on a version of Causal Dynamical Triangulations which incorporates topology change, has recently been formulated…
Topology change in causal quantum gravity
J. Ambjorn, R. Loll, Y. Watabiki +2
The role of topology change in a fundamental theory of quantum gravity is still a matter of debate. However, when regarding string theory as two-dimensional quantum gravity, topolo…
