Spreading of damage in a 3D Ising spin glass

The authors study the time evolution of the Hamming distance of two configurations by Monte Carlo simulation, differing only by the central spin, of the +or-J 3D Ising spin glass. They observe two temperature regimes: a high-temperature one where the damage readily spreads and a low-temperature one where the spreading of damage is hindered. The critical temperature numerically coincides with the spin-glass temperature found by Monte Carlo simulation.
