Outline of Final Research Achievements

In order to lay a future foundation for a microscopic theory of plastic flows, an idea of importing the Lagrangian correlation, also known as the label variable method, into the statistical theory of dense colloidal liquids from the theory of fluid turbulence was tested and developed. The usefulness of this idea was demonstrated by analytical calculation of four-point space-time correlations in single-file diffusion in one-dimensional colloidal systems; besides, the label variable method is shown to be extensible to the two-dimensional cases.
