Viscosity anomaly in core-softened liquids [PDF]
Yu. D. Fomin, V. N. RyzhovThe 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.View original: http://arxiv.org/abs/1303.4204
