SHEAR VISCOSITY FROM A DYNAMIC DENSITY-FUNCTIONAL THEORY

Based on a dynamic version of the density-functional theory, we obtain a stationary density profile around a particle in a shear flow and calculate the shear viscosity of monatomic liquids. Our results are compared with those obtained from both equilibrium and nonequilibrium computer experiments. An approach similar to the one developed for the shear viscosity is suggested, which in principle enables us to calculate a friction constant and consequently a self-diffusion constant, and some results from the zeroth order approximation are presented.
