Phase diagram of four-dimensional dynamical triangulations with a boundary
Simeon Warner, Simon Catterall
We report on simulations of DT simplicial gravity for manifolds with the topology of the 4-disk. We find evidence for four phases in a two-dimensional parameter space. In two of th…
Phase diagram of three-dimensional dynamical triangulations with a boundary
Simeon Warner, Simon Catterall, Ray Renken
We use Monte Carlo simulation to study the phase diagram of three-dimensional dynamical triangulations with a boundary. Three phases are indentified and characterized. One of these…
The Block Spin Renormalization Group Approach and Two-Dimensional Quantum Gravity
Ray Renken
A block spin renormalization group approach is proposed for the dynamical triangulation formulation of two-dimensional quantum gravity. The idea is to update link flips on the bloc…
Ising-link Quantum Gravity
Tom Fleming, Mark Gross, Ray Renken
We define a simplified version of Regge quantum gravity where the link lengths can take on only two possible values, both always compatible with the triangle inequalities. This is…
