The spreading of the Hamming distance or damage has been investigated for +/- J Ising spin glasses under heat bath dynamics. Dimensions d = 2, 3, 4, 6 and mean field were studied. For finite dimensions, the damage goes to zero at long times above a temperature T(D)(d). Accurate values of this critical temperature were obtained, together with certain critical exponents. The spin glass ordering temperatures T(g) were also estimated from the damage spreading data. The results are compared with other work and discussed from a phase space approach.

Abstract
The spreading of the Hamming distance or damage has been investigated for +/- J Ising spin glasses under heat bath dynamics. Dimensions d = 2, 3, 4, 6 and mean field were studied. For finite dimensions, the damage goes to zero at long times above a temperature T(D)(d). Accurate values of this critical temperature were obtained, together with certain critical exponents. The spin glass ordering temperatures T(g) were also estimated from the damage spreading data. The results are compared with other work and discussed from a phase space approach.File in questo prodotto:
