A Causal Alternative for c=0 Strings
J. Ambjorn, R. Loll, Y. Watabiki +2
We review a recently discovered continuum limit for the one-matrix model which describes "causal" two-dimensional quantum gravity. The behaviour of the quantum geometry in this lim…
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.…
Shaken, but not stirred - Potts model coupled to quantum gravity
J. Ambjorn, K. N. Anagnostopoulos, R. Loll +1
We investigate the critical behaviour of both matter and geometry of the three-state Potts model coupled to two-dimensional Lorentzian quantum gravity in the framework of causal dy…
The Self-Organized de Sitter Universe
J. Ambjorn, J. Jurkiewicz, R. Loll
We propose a theory of quantum gravity which formulates the quantum theory as a nonperturbative path integral, where each spacetime history appears with a weight given by the expon…
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…
