dc.description.abstract |
Liquids relax extremely slowly on approaching the glass state. One explanation is
that an entropy crisis, due to the rarefaction of available states, makes it increasingly
arduous to reach equilibrium in that regime. Validating this scenario is challenging,
because experiments offer limited resolution, while numerical studies lag more than
eight orders of magnitude behind experimentally-relevant timescales. In this work
we not only close the colossal gap between experiments and simulations but manage
to create in-silico configurations that have no experimental analog yet. Deploying
a range of computational tools, we obtain four estimates of their configurational
entropy. These measurements consistently confirm that the steep entropy decrease observed
in experiments is found also in simulations even beyond the experimental glass transition.
Our numerical results thus open a new observational window into the physics of glasses
and reinforce the relevance of an entropy crisis for understanding their formation.
