Lattice Models of Quantum Gravity
E. Bittner, A. Hauke, C. Holm +3
Standard Regge Calculus provides an interesting method to explore quantum gravity in a non-perturbative fashion but turns out to be a CPU-time demanding enterprise. One therefore s…

Nonperturbative Studies of Quantum Gravity
Wolfgang Beirl, Harald Markum, Juergen Riedler
We investigate quantum gravity in the path integral formulation using the Regge calculus. Restricting the quadratic link lengths of the originally triangular lattice the path integ…

On the Measure of Simplicial Quantum Gravity in Four Dimensions
W. Beirl, H. Markum, J. Riedler
We study quantum gravity in the path-integral formulation using the Regge calculus. In spite of the unbounded gravitational action the existence of an entropy-dominated phase is co…
