Abstract
We numerically study the three-dimensional Edwards-Anderson model with Gaussian
couplings, focusing on the heterogeneities arising in its nonequilibrium dynamics. Results
are analyzed in terms of the backbone picture, which links strong dynamical
heterogeneities to spatial heterogeneities emerging from the correlation of local rigidity
of the bond network. Different two-times quantities as the flipping time distribution and
the correlation and response functions, are evaluated over the full system and over high-
and low-rigidity regions. We find that the nonequilibrium dynamics of the model is highly
correlated to spatial heterogeneities. Also, we observe a similar physical behavior to
that previously found in the Edwards-Anderson model with a bimodal (discrete) bond
distribution. Namely, the backbone behaves as the main structure that supports the
spin-glass phase, within which a sort of domain-growth process develops, while the
complement remains in a paramagnetic phase, even below the critical temperature.
