Molecular-dynamics study of long-lived structures in a fragile glass-forming liquid

This is the authors' abstract. We don't add key points for this paper.

We present molecular-dynamics results for a two-component, two-dimensional Lennard-Jones supercooled liquid near the glass transition. We find that the supercooled liquid is spatially heterogeneous and that there are long-lived clusters whose size distribution satisfies a scaling relation up to a cutoff. The similarity of several properties of the supercooled liquid to those of a mean-field glass-forming fluid near the spinodal suggests that the glass transition in the supercooled liquid is associated with an underlying thermodynamic instability.
