Geodesic distances in Liouville quantum gravity
Jan Ambjorn, Timothy Budd
In order to study the quantum geometry of random surfaces in Liouville gravity, we propose a definition of geodesic distance associated to a Gaussian free field on a regular lattic…
The toroidal Hausdorff dimension of 2d Euclidean quantum gravity
Jan Ambjorn, Timothy Budd
The lengths of shortest non-contractible loops are studied numerically in 2d Euclidean quantum gravity on a torus coupled to conformal field theories with central charge less than…
Trees and spatial topology change in CDT
Jan Ambjorn, Timothy G. Budd
Generalized causal dynamical triangulations (generalized CDT) is a model of two-dimensional quantum gravity in which a limited number of spatial topology changes is allowed to occu…
Semi-classical Dynamical Triangulations
Jan Ambjorn, Timothy G. Budd
For non-critical string theory the partition function reduces to an integral over moduli space after integrating over matter fields. The moduli integrand is known analytically for…
Roaming moduli space using dynamical triangulations
J. Ambjorn, J. Barkley, T. Budd
In critical as well as in non-critical string theory the partition function reduces to an integral over moduli space after integration over matter fields. For non-critical string t…
Baby Universes Revisited
J. Ambjorn, J. Barkley, T. Budd +1
The behaviour of baby universes has been an important ingredient in understanding and quantifying non-critical string theory or, equivalently, models of two-dimensional Euclidean q…
