Correlation functions in lattice formulations of quantum gravity
W. Beirl, A. Hauke, P. Homolka +2
We compare different models of a quantum theory of four-dimensional lattice gravity based on Regge's original proposal. From Monte Carlo simulations we calculate two-point function…

The phase structure of pure Regge gravity
W. Beirl, A. Hauke, P. Homolka +4
We examine the phase structure of pure Regge gravity in four dimensions and compare our Monte Carlo results with -link Regge-theory as well as with another formulation of latt…

Quantum gravity and spin systems
W. Beirl, P. Homolka, B. Krishnan +2
A new method for nonperturbative investigations of quantum gravity is presented in which the simplicial path integral is approximated by the partition function of a spin system. Th…
