摘要: By a molecular-dynamics simulation of three-dimensional system 4000 particles, we show that the long-time tail velocity autocorrelation function has form ${\ensuremath{\alpha}}_{0}{t}^{\ensuremath{-}\frac{3}{2}}$, where $t$ is time and ${\ensuremath{\alpha}}_{0}$ coefficient depending on kinematic viscosity diffusion coefficient.
