Abstract
We have performed a very accurate computation of the nonequi-librium fluctuation–dissipation ratio for the 3D Edwards–AndersonIsing spin glass, by means of large-scale simulations on the special-purpose computers Janus and Janus II. This ratio (computed forfinite times on very large, effectively infinite, systems) is comparedwith the equilibrium probability distribution of the spin overlapfor finite sizes. Our main result is a quantitative statics-dynamicsdictionary, which could allow the experimental exploration ofimportant features of the spin-glass phase without requiringuncontrollable extrapolations to infinite times or system sizes| File | Dimensione | Formato | |
