Abstract

The most puzzling aspect of the glass transition observed in laboratory is the decoupling of the dynamics from the structure. As an attempt to reconcile the dynamic and the static lengthscales associated with the glass problem, we discuss the apparent correlations between the static relaxation length, defined as that lengthscale over which the potential energy fluctuation is correlated, with the linear size of the dynamic heterogeneity. The dynamic heterogeneous domains with long life-times, may therefore be linked to the droplets of low potential energy, or the tightly bound regions inside the liquid.
