Scaling Behavior in 4D Simplicial Quantum Gravity
Scaling relations in four-dimensional simplicial quantum gravity are proposed using the concept of the geodesic distance. Based on the analogy of a loop length distribution in the two-dimensional case, the scaling relations of the boundary volume distribution in four dimensions are discussed in three regions: the strong-coupling phase, the critical point and the weak-coupling phase. In each pha...
متن کاملTopology in 4d Simplicial Quantum Gravity
We simulate 4d simplicial gravity for three topologies S, S S and S S S S and show that the free energy for these three xed topology ensembles is the same in the thermodynamic limit N4 !1. We show, that the next-to-leading order corrections, at least away from the critical point, can be described by kinematic sources.
متن کاملCrumpled Triangulations and Critical Points in 4D simplicial quantum gravity
We estimate analytically the critical coupling separating the weak and the strong coupling regime in 4D simplicial quantum gravity to be located at kcrit 2 ≃ 1.3093. By carrying out a detailed geometrical analysis of the strong coupling phase we argue that the distribution of dynamical triangulations with singular vertices, dominating in such a regime, is characterized by distinct sub-dominatin...
متن کاملCritical Behavior in Simplicial Quantum Gravity
Four-dimensional quantum gravity is a complex theory due to the unboundedness of the pure gravitational action, its non-renormalizability and non-polynomial nature 1. We will concentrate here on the simplicial formulation of quantum gravity also known as Regge calculus (for a review, see refs. 2,3). One of the advantages of the approach lies in the fact that it can be formulated in any space-ti...
متن کامل4D simplicial quantum gravity with a nontrivial measure.
We study 4d simplicial quantum gravity in the dynamical triangulation approach with a non-trivial class of measures. We find that the measure contribution plays an important role, influencing the phase diagram and the nature of the (possible) critical theory. We discuss how the lattice theory could be used to fix the quantum measure in a non-ambiguous
