Two-Point Functions of Four-Dimensional Simplicial Quantum Gravity
W. Beirl, H. Markum, J. Riedler
Abstract
We investigate the interaction mechanism of pure quantum gravity in Regge discretization. We compute volume-volume and link-link correlation functions. In a preliminary analysis the forces turn out to be of Yukawa type, at least on our finite lattice being away from the continuum limit.
