Resumen:
The discovery that the propensity for particle motion in a supercooled liquid is completely determined
by the initial structure pointed to the existence of a causal link between structure and dynamics in glassy
systems. Here we demonstrate that this underlying influence of structure is only local in time, fading out
beyond the metabasin lifetime much before the relaxation time. Thus, our results reveal the
irreproducibility of metabasin dynamics and support the scenario of a random walk on metabasins for
the long time diffusion.
