DAMAGE SPREADING IN + -J ASYMMETRIC ISING SPIN-GLASSES/

Spin glasses in dimensions 2, 3, 4 and mean field are studied numerica lly as a function of the degree of asymmetry of the interactions betwe en spins. Damage spreading data are used to assess the effects on the spin glass ordering of introducing asymmetry in the couplings. In all dimensions the critical temperature for damage spreading is rather ins ensitive to the asymmetry, but the spin glass ordering is strongly sup pressed by any finite degree of asymmetry. We discuss the physical sig nificance of the damage spreading parameter.
