Physics:Krausser–Samwer–Zaccone equation

The Krausser–Samwer–Zaccone equation describes the viscosity of liquids, including supercooled liquids upon approaching the glass transition, in terms of physical parameters; it is named after J. Krausser, and Alessio Zaccone. The Krausser–Samwer–Zaccone equation for the viscosity of a liquid reads:

$\eta =\exp \{\frac{V_c{C}_G}{k_{B}T}\exp [(2+\lambda ){\alpha }_T{T}_g(1-\frac{T}{T_g})]\}$

where ${\alpha }_T$ is the thermal expansion coefficient of the liquid, and $\lambda$ is a parameter which measures the steepness of the repulsive part of the interatomic potential.
