FIG. 3.

Propagation of plastic events. (a) Evolution of the probability field $\mathrm{\varphi }$ at $p_0=3.72$. Bright regions indicate a high probability of finding another rearrangement in the region relative to the causal rearrangement. (b) Spatial distribution of the correlation field ${\mathrm{\varphi }}_x$ as a function of the relative horizontal position $\mathrm{\Delta }x$. The distribution has a diffusing bimodal shape, indicating a convection process alongside diffusion. (c) Spatial distribution of the correlation field ${\mathrm{\varphi }}_y$ as a function of the relative vertical position $\mathrm{\Delta }y$. The distribution is bell-shaped, with the width of the bell increasing as time progresses, indicating a pure diffusion process. (d) The separation of the peaks in ${\mathrm{\varphi }}_x$ and the Full Width at Half Maximum (FWHM) of ${\mathrm{\varphi }}_y$ as functions of the time lag $\mathrm{\Delta }t$.
