Topology Change and the Emergence of Geometry in Two Dimensional Causal Quantum Gravity
Willem Westra
In this thesis we analyze a very simple model of two dimensional quantum gravity based on causal dynamical triangulations (CDT). We present an exactly solvable model which indicate…
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…
A String Field Theory based on Causal Dynamical Triangulations
J. Ambjorn, R. Loll, Y. Watabiki +2
We formulate the string field theory in zero-dimensional target space corresponding to the two-dimensional quantum gravity theory defined through Causal Dynamical Triangulations. T…
Space-time foam in 2D and the sum over topologies
R. Loll, W. Westra
It is well-known that the sum over topologies in quantum gravity is ill-defined, due to a super-exponential growth of the number of geometries as a function of the space-time volum…
