Causal 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 کامل(2+1)-Dimensional Quantum Gravity as the Continuum Limit of Causal Dynamical Triangulations
We perform a non-perturbative sum over geometries in a (2+1)-dimensional quantum gravity model given in terms of Causal Dynamical Triangulations. Inspired by the concept of triangulations of product type introduced previously, we impose an additional notion of order on the discrete, causal geometries. This simplifies the combinatorial problem of counting geometries just enough to enable us to c...
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 کاملReview on Causal Dynamical Triangulation as a candidate of the quantum theory of gravity
In this undergraduate research opportunities program in science (UROPS), we study one of the most successful candidates of the theory of quantum gravity, the Causal Dynamical Triangulation (CDT). The project was motivated by the publication [1] by Ambjørn, Jurkiewicz and Loll in the success of CDT producing the correct dimension of our universe in 2004. It marked the first time that a candidate...
متن کاملRemarks 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...
