Asymptotic Behavior of the Green-Kubo Integrands in Binary Mixtures

Abstract

In binary mixtures, as in monatomic fluids, the time dependent Green‐Kubo autocorrelation functions decrease as t^−d/2 for large times $\mathrm{(d\; =}\mathrm{dimensionality}\text{≥ 3)}$ . In 3d binary mixtures, the space dependent auto‐correlation functions decrease at large distances as R⁻⁴ for the diffusion and thermodiffusion coefficients and as R^−7/2 for the shear and bulk viscosity and heat conductivity.
