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 and temporal autocorrelation function of the local tetrahedral order parameter . Using computer simu…
Correspondence Between the Phase Diagrams of TIP5P Water and a Spherically Symmetric Repulsive Ramp Potential
Zhenyu Yan, Sergey V. Buldyrev, Pradeep Kumar +2
We perform molecular dynamics simulations of a well-known water model (the TIP5P pair potential) and a simple liquid model (a two-scale repulsive ramp potential) to compare the reg…
Structure of the First and Second Neighbor Shells of Water: Quantitative Relation with Translational and Orientational Order
Zhenyu Yan, Sergey V. Buldyrev, Pradeep Kumar +3
We perform molecular dynamics simulation of water using the TIP5P model to quantify structural order in both the first shell (defined by four nearest neighbors)and second shell (de…
Breakdown of the Stokes-Einstein Relation in Supercooled Water
Pradeep Kumar, S. V. Buldyrev, S. R. Becker +3
Supercooled water exhibits a breakdown of the Stokes-Einstein relation between the diffusion constant and the alpha relaxation time . For water simulated with the TIP5P an…
A Physical Mechanism Underlying the Increase of Aqueous Solubility of Nonpolar Compounds and the Denaturation of Proteins upon Cooling
Sergey V. Buldyrev, Pradeep Kumar, H. Eugene Stanley
The increase of aqueous solubility of nonpolar compounds upon cooling and the cold denaturation of proteins are established experimental facts. Both phenomena have been hypothesize…
Short-ranged attractive colloids: What is the gel state ?
E. Zaccarelli, F. Sciortino, S. V. Buldyrev +1
We evaluate thermodynamic, geometric and dynamic properties of a short-ranged square well binary mixture to provide a coherent picture of this simple, but rich, model for colloidal…
