Z_2-Regge versus Standard Regge Calculus in two dimensions
E. Bittner, A. Hauke, H. Markum +3
We consider two versions of quantum Regge calculus. The Standard Regge Calculus where the quadratic link lengths of the simplicial manifold vary continuously and the Z_2-Regge Mode…
2d quantum gravity with discrete edge lengths
E. Bittner, H. Markum, J. Riedler
An approximation of the Standard Regge Calculus (SRC) was proposed by the -Regge Model (RM). There the edge lengths of the simplicial complexes are restricted to only two…
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…
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…
Phase diagram of Regge quantum gravity coupled to SU(2) gauge theory
B. A. Berg, W. Beirl, B. Krishnan +2
We analyze Regge quantum gravity coupled to SU(2) gauge theory on , and simplicial lattices. It turns out that the window of the well-d…
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…
