Remanent magnetization of the infinite-range Ising spin glass

Abstract

The remanent magnetization $M_r$ and the excess energy ΔE are studied for the Sherrington-Kirpatrick model of spin glasses using Monte Carlo simulations. At zero temperature T the system relaxes to a stationary nonequilibrium state with nonzero $M_r$ and ΔE; both quantities are self-averaging. For 0$T_c$ the simulations indicate that $M_r$ and ΔE decay to zero as a power law in time.
