The Universe from Scratch
R. Loll, J. Ambjorn, J. Jurkiewicz
A fascinating and deep question about nature is what one would see if one could probe space and time at smaller and smaller distances. Already the 19th-century founders of modern g…
Semiclassical Universe from First Principles
J. Ambjorn, J. Jurkiewicz, R. Loll
Causal Dynamical Triangulations in four dimensions provide a background-independent definition of the sum over space-time geometries in nonperturbative quantum gravity. We show tha…
3D Lorentzian Quantum Gravity from the asymmetric ABAB matrix model
J. Ambjorn, J. Jurkiewicz, R. Loll +1
The asymmetric ABAB-matrix model describes the transfer matrix of three-dimensional Lorentzian quantum gravity. We study perturbatively the scaling of the ABAB-matrix model in the…
Renormalization of 3d quantum gravity from matrix models
J. Ambjorn, J. Jurkiewicz, R. Loll
Lorentzian simplicial quantum gravity is a non-perturbatively defined theory of quantum gravity which predicts a positive cosmological constant. Since the approach is based on a su…
