Particle dynamics in view of dynamical density functional theory

Strongly correlated dynamics of fluid particles in a supercooled liquid is discussed on the basis of the mesoscopic kinetic equation involved in the dynamical density functional theory, focusing attention on the advantage of a spatio-temporally coarse-grained description. By virtue of the coarse-grained character, the time evolution of the density profile is effectively obtainable beyond the late β-relaxation regime, skipping over microscopic processes. Application of the theory is proposed in discussing the correlation length of particle motion, which may be crucial in examining the effect of confinement.
