Summing over all Topologies in CDT String Field Theory
J. Ambjorn, R. Loll, W. Westra +1
By explicitly allowing for topology to change as a function of time, two-dimensional quantum gravity defined through causal dynamical triangulations gives rise to a new continuum s…

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…

Nonperturbative sum over topologies in 2D Lorentzian quantum gravity
R. Loll, W. Westra, S. Zohren
The recent progress in the Causal Dynamical Triangulations (CDT) approach to quantum gravity indicates that gravitation is nonperturbatively renormalizable. We review some of the l…
