The Renormalization Group and Dynamical Triangulations
A block spin renormalization group approach is introduced which can be applied to dynamical triangulations in any dimension.
متن کاملA Renormalization Group for Dynamical Triangulations in Arbitrary Dimensions
A block spin renormalization group approach is proposed for the dynamical triangulation formulation of quantum gravity in arbitrary dimensions. Renormalization group flow diagrams are presented for the three-dimensional and four-dimensional theories near their respective transitions. PACS numbers: 04.60.+n, 05.70.Jk, 11.10.Gh
متن کاملA statistical formalism of Causal Dynamical Triangulations
We rewrite the 1+1 Causal Dynamical Triangulations model as a spin system and thus provide a new method of solution of the model. Email address: [email protected] Email address: [email protected] 1
متن کاملCoarse-graining dynamical triangulations: a new scheme
A new procedure for coarse-graining dynamical triangulations is presented. The procedure provides a meaning for the relevant value of observables when “probing at large scales”, e.g. the average scalar curvature. The scheme may also be useful as a starting point for a new type of renormalisation procedure, suitable for dynamically triangulated quantum gravity. Random Delaunay triangulations hav...
متن کاملGauge fixing in Causal Dynamical Triangulations
We relax the definition of the Ambjørn-Loll causal dynamical triangulation model in 1 + 1 dimensions to allow for a varying lapse. We show that, as long as the spatially averaged lapse is constant in time, the physical observables are unchanged in the continuum limit. This supports the claim that the time slicing of the model is the result of a gauge fixing, rather than a physical preferred tim...
