Focusing on the Fixed Point of 4d Simplicial Gravity
نویسندگان
چکیده
Our earlier renormalization group study of simplicial gravity is extended and the evidence for the existence of an isolated ultra-violet fixed point is strengthened. A high statistics study of the volume and coupling constant dependence of the cumulants of the node distribution is carried out. It appears that the phase transition of the theory is of first order, contrary to what is generally believed . January 1996 LPTHE Orsay 96/08 BI-TP 96/05 ITFA-96-2 Permanent address: Inst. Comp.

Topology 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.

A thorough numerical examination for the field theory of 4D quantum gravity (QG) with a special emphasis on the conformal mode dependence has been studied. More clearly than before, we obtain the string susceptibility exponent of the partition function by using the Grand-Canonical Monte-Carlo method. Taking thorough care of the update method, the simulation is made for 4D Euclidean simplicial m...

Four-dimensional(4D) spacetime structures are investigated using the concept of the geodesic distance in the simplicial quantum gravity. On the analogy of the loop length distribution in 2D case, the scaling relations of the boundary volume distribution in 4D are discussed in various coupling regions i.e. strong-coupling phase, critical point and weak-coupling phase. In each phase the different...

The phase transition of 4D simplicial quantum gravity coupled to U (1) gauge fields is studied using Monte-Carlo simulations. The phase transition of the dynamical triangulation model with vector field (NV = 1) is smooth as compared with the pure gravity(NV = 0). The node susceptibility (χ) is studied in the finite size scaling method. At the critical point, the node distribution has a sharp pe...
