Proper time is stochastic time in 2d quantum gravity
J. Ambjorn, R. Loll, Y. Watabiki +2
We show that proper time, when defined in the quantum theory of 2d gravity, becomes identical to the stochastic time associated with the stochastic quantization of space. This obse…
New aspects of two-dimensional quantum gravity
J. Ambjorn, R. Loll, Y. Watabiki +2
Causal dynamical triangulations (CDT) can be used as a regularization of quantum gravity. In two dimensions the theory can be solved anlytically, even before the cut-off is removed…
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 causal perspective on random geometry
Stefan Zohren
In this thesis we investigate the importance of causality in non-perturbative approaches to quantum gravity. Firstly, causal sets are introduced as a simple kinematical model for c…
