Remarks on the quantum gravity interpretation of 4D dynamical triangulation
Here the path integral is over real metrics modulo coordinate transformations, G denotes a renormalized Newton constant and the · · · indicate higher derivative terms like R, etc. There may also be nonlocal terms related to the conformal anomaly [2]. The integral over μ produces the volume fixing delta function δ( ∫ dx √ g − V ). If this integral were done in the saddle point approximation, the...
متن کاملNumerical Quantum Gravity by Dynamical Triangulation
Recently an alternate technique for numerical quantum gravity, dynamical triangulation, has been developed. In this method, the geometry is varied by adding and subtracting equilateral simplices from the simplicial complex. This method overcomes certain difficulties associated with the traditional approach in Regge calculus of varying geometry by varying edge lengths. However additional complic...
متن کاملCausal Dynamical Triangulation of Quantum Gravity in Three Dimensions
The theory of causal dynamical triangulation in (2+1) dimensions is studied through the help of Monte Carlo simulations. The basic ideas behind this particular approach to quantum gravity are outlined in the paper. The numerical setup and the results from the simulations are presented and discussed. Based on the numerical results, the theory is shown to possess a non-trivial classical limit. Th...
متن کاملTwo-point functions in 4D dynamical triangulation
In the dynamical triangulation model of 4D euclidean quantum gravity we measure two-point functions of the scalar curvature as a function of the geodesic distance. To get the correlations it turns out that we need to subtract a squared one-point function which, although this seems paradoxical, depends on the distance. At the transition and in the elongated phase we observe a power law behaviour...
متن کاملCorrelations and Binding in 4D Dynamical Triangulation
Here N2 is the number of triangles in the simplicial manifold consisting of N4 four-simplices and the topology is chosen to be that of S. (For more details see [1].) We recall that the system has two phases, a crumpled phase at low κ2 and an elongated phase at high κ2. The model is supposed to represent the quantum gravitational path integral over euclidean spacetimes weighted with the Regge-Ei...
