Calculation of dispersion of transport coefficients and dynamical structure factor on the basis of Fokker-Plank equation for nonequilibrium distribution function of collective variables.

V.V. Ignatjuk
M.V. Tokarchuk

On the base of modes-coupling theory one has obtained the expressions for time-spatial dispersion of transport coefficients of simple liquid. Numerical calculation of dynamical structure factor has been performed both in local thermodynamic approximation and nonlocal thermodynamic approximation. The analysis of sound mode has been carried out and coefficient at nonanalytical term ($\sim k^{5/2}$) in the expression for sound frequency has been calculated. Results obtained are being compared with molecular dynamic data and neutron scattering experiment.
