Phase Structure of SU(2) Lattice Gauge Theory with Quantum Gravity

Abstract

We investigate 4$d$ SU(2) lattice gauge theory with Regge--Einstein quantum gravity on a dynamically coupled Regge skeleton. To overview the phase diagram we perform simulations on a small $2\cdot 4^3$ system. Evidence for an entropy--dominated disordered, an entropy--dominated ordered and an ill--defined region is presented.
