Phase Structure of Four Dimensional Simplicial Quantum Gravity
We present the results of a high statistics Monte Carlo study of a model for four dimensional euclidean quantum gravity based on summing over triangulations. We show evidence for two phases; in one there is a logarithmic scaling of the mean linear extent with volume, whilst the other exhibits power law behaviour with exponent 1 2 . We are able to extract a finite size scaling exponent governing...
متن کاملNonuniform measure in four-dimensional simplicial quantum gravity.
Four-dimensional euclidean quantum gravity has been studied as a discrete model based on dynamical triangulations by Ambjørn and Jurkiewicz and by Agishtein and Migdal. We discuss a particular implementation of a Monte Carlo simulation of simplicial quantum gravity. As an application we introduce a non-uniform measure and examine its effect on simple aspects of the mathematical geometry. We fin...
متن کاملCritical Properties of Two-dimensional Simplicial Quantum Gravity
Simplicial higher-derivative quantum gravity is investigated in two dimensions for a manifold of toroidal topology. The manifold is dynamically triangulated using Regge’s formulation of gravity, with continuously varying edge lengths and fiied coordination number. Critical exponents are estimated by computer simulation on lattices with up to 786432 edges, and compared to the continuum conformal...

متن کاملOn the Measure of Simplicial Quantum Gravity in Four Dimensions
where n(IE) denotes the state density for a given value IE of the action, i.e. the number of configurations with the same Euclidean action. If n(IE) vanishes fast enough for IE → −∞ the integral (6) stays finite in a certain range of β. This means that there are many configurations with small action and only few giving a large average curvature; the larger the curvature the smaller its probabil...
