Linking dynamical heterogeneity to static amorphous order
Abstract
© 2016 IOP Publishing Ltd and SISSA Medialab srl. Glass-forming liquids grow dramatically
sluggish upon cooling. This slowdown has long been thought to be accompanied by a
growing correlation length. Characteristic dynamical and static length scales, however,
have been observed to grow at different rates, which perplexes the relationship between
the two and with the slowdown. Here, we show the existence of a direct link between
dynamical sluggishness and static point-to-set correlations, holding at the local
level as we probe different environments within a liquid. This link, which is stronger
and more general than that observed with locally preferred structures, suggests the
existence of an intimate relationship between structure and dynamics in a broader
range of glass-forming liquids than previously thought.
