More on the Exponential Bound of four dimensional simplicial quantum gravity
Physics Letters B, 1995Co-Authors: Bernd Brugmann, Enzo MarinariAbstract:A crucial requirement for the standard interpretation of Monte Carlo simulations of simplicial quantum gravity is the existence of an Exponential Bound that makes the partition function well-defined. We present numerical data favoring the existence of an Exponential Bound, and we argue that the more limited data sets on which recently opposing claims were based are also consistent with the existence of an Exponential Bound.Comment: 10 pages, latex, 2 figure

on the Exponential Bound in four dimensional simplical gravity
Physics Letters B, 1994Co-Authors: J Ambjorn, J JurkiewiczAbstract:Abstract Simplical quantum gravity has been proposed as a regularization for four dimensional quantum gravity. The partition function is constructed by performing a weighted sum over all triangulations of the 4-sphere. The model is well-defined only if the number of such triangulations consisting of N simplexes is Exponentially Bounded. Numerical simulations seem so far to favor such a Bound.

Is there an Exponential Bound in four-dimensional simplicial gravity?
Physical Review Letters, 1994Co-Authors: Simon Catterall, John B. Kogut, R. RenkenAbstract:We have studied a model which has been proposed as a regularisation for four dimensional quantum gravity. The partition function is constructed by performing a weighted sum over all triangulations of the four sphere. Using numerical simulation we find that the number of such triangulations containing V simplices grows faster than Exponentially with V . This property ensures that the model has no thermodynamic limit.

Baby universes in 4D dynamical triangulation
Physics Letters B, 1996Co-Authors: Simon Catterall, John B. Kogut, R. Renken, G. ThorleifssonAbstract:Abstract We measure numerically the distribution of baby universes in the crumpled phase of the dynamical triangulation model of 4D quantum gravity. The relevance of the results to the issue of an Exponential Bound is discussed. The data are consistent with the existence of such a Bound.
