Viscosity anomaly in core-softened liquids
arXiv:1303.4204 · doi:10.1016/j.physleta.2013.04.003
Abstract
The present article presents a molecular dynamics study of several anomalies of core-softened systems. It is well known that many core-softened liquids demonstrate diffusion anomaly. Usual intuition relates the diffusion coefficient to shear viscosity via Stockes-Einstein relation. However, it can break down at low temperature. In this respect it is important to see if viscosity also demonstrates anomalous behavior.
