Space-Time Correlations in the Orientational Order Parameter and the Orientational Entropy of Water

Pradeep Kumar, Sergey V. Buldyrev, H. Eugene Stanley

We introduce the spatial correlation function $C_Q(r)$ and temporal autocorrelation function $C_Q(t)$ of the local tetrahedral order parameter $Q\equiv Q(r,t)$. Using computer simu…
