Title: Decay of Time Correlations in Two Dimensions
Abstract:Molecular-dynamic studies of the kinetic correlation functions for shear viscosity and heat conductivity of hard disks are consistent with the asymptotic reciprocal time behavior $\frac{1}{S}$ predict...Molecular-dynamic studies of the kinetic correlation functions for shear viscosity and heat conductivity of hard disks are consistent with the asymptotic reciprocal time behavior $\frac{1}{S}$ predicted by hydrodynamics. However, this hydrodynamic description, which predicts divergent transport coefficients, must be made self-consistent by introducing time-dependent transport coefficients, leading to a decay of $\frac{1}{S\sqrt{(\mathrm{ln}S)}}$, indistinguishable from the $\frac{1}{S}$ behavior. The hydrodynamic model predicts no such long-time behavior for the potential contributions.Read More
