Correlation of the scaling exponent of the diffusivity-density function in viscous liquids with their elastic properties
arXiv:1003.3559 · doi:10.1063/1.3382645
Abstract
Fundamental thermodynamical concepts and a solid-state point defect elastic model are used to formulate a diffusivity-density scaling function for viscous liquids. It is proved in a straightforward manner that the scaling exponent describing the density scaling of the diffusivity, is related with the pressure derivative of the isothermal bulk modulus.
