Remarks on Holographic Wilson Loops and the Schwinger Effect
Jan Ambjorn, Yuri Makeenko
We extend Douglas' solution of the problem of finding minimal surfaces to anti-de Sitter space. The case of a circle as a boundary contour is elaborated. We discuss applications to…
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…
A second-order phase transition in CDT
J. Ambjorn, S. Jordan, J. Jurkiewicz +1
Causal Dynamical Triangulations (CDT) are a concrete attempt to define a nonperturbative path integral for quantum gravity. We present strong evidence that the lattice theory has a…
Lattice quantum gravity - an update
J. Ambjorn, J. Jurkiewicz, R. Loll
We advocate lattice methods as the tool of choice to constructively define a background-independent theory of Lorentzian quantum gravity and explore its physical properties in the…
CDT as a scaling limit of matrix models
Jan Ambjorn
It is shown that generalized CDT, the two-dimensional theory of quantum gravity, constructed as a scaling limit from so-called causal dynamical triangulations, can be obtained from…
The Semiclassical Limit of Causal Dynamical Triangulations
J. Ambjorn, A. Gorlich, J. Jurkiewicz +3
Previous work has shown that the macroscopic structure of the theory of quantum gravity defined by causal dynamical triangulations (CDT) is compatible with that of a de Sitter univ…
