Geometrical aspects of the Z-invariant Ising model
Ruben Costa-Santos
We discuss a geometrical interpretation of the Z-invariant Ising model in terms of isoradial embeddings of planar lattices. The Z-invariant Ising model can be defined on an arbitra…

Space-time foam in 2D and the sum over topologies
R. Loll, W. Westra
It is well-known that the sum over topologies in quantum gravity is ill-defined, due to a super-exponential growth of the number of geometries as a function of the space-time volum…

Determinism beneath Quantum Mechanics
Gerard 't Hooft
Contrary to common belief, it is not difficult to construct deterministic models where stochastic behavior is correctly described by quantum mechanical amplitudes, in precise accor…
