Abstract
We have computed the exact partition function of the 3D Ising spin glass on lattices of effective size 3×3×Lz, 4×4×Lz, and 5×5×Lz forL z up to 9, and several random bond configurations. Studying the distribution of zeros of the associated partition functions, we find further evidence that these systems have a singularity in the thermodynamic limit.
