Decorating Random Quadrangulations
D. A. Johnston, R. P. K. C. Malmini
On various regular lattices (simple cubic, body centred cubic..) decorating an edge with an Ising spin coupled by bonds of strength L to the original vertex spins and competing wit…

2D Lorentzian Gravity as 2D Euclidean Gravity with Ising Spins
W. Beirl, D. A. Johnston
We suggest a generalization of the dynamical triangulation approach to quantum gravity with both timelike and spacelike edges, which can serve as a toy model for quantum gravity in…
