Connection between Adam-Gibbs theory and spatially heterogeneous dynamics

We investigate the spatially heterogeneous dynamics in the extended simple point charge model of water using molecular dynamics simulations. We relate the average mass n(*) of mobile particle clusters to the diffusion constant and the configurational entropy. Hence, n(*) can be interpreted as the mass of the cooperatively rearranging regions that form the basis of the Adam-Gibbs theory of the dynamics of supercooled liquids. We also examine the time and temperature dependence of these transient clusters.
