The importance of the dynamic anomaly of the self-diffusion coefficient, which becomes zero at the colloidal glass transition volume fraction φg as DS∼(1−Φ(x,t)/φg)2, has recently been emphasized for understanding structural slowing down in concentrated hard-sphere colloidal suspensions,...

The numerical solutions of the mode-coupling equations for the Lennard-Jones binary colloids are investigated by extensive Brownian-dynamics simulations from a unified point of view based on the mean-field theory proposed recently by one of the present authors [M. Tokuyama, Physica A 378 (2007)...

This paper compares simulation and experiment to verify how a hard-sphere fluid is different from a suspension of hard-sphere colloids near the glass transition at 6% polydispersity. This is done by performing extensive molecular-dynamic simulations and by analyzing the resultant mean-square...

A statistical-mechanical theory of self-diffusion in colloidal suspensions is presented. A renormalized linear Langevin equation is derived from a nonlinear Langevin equation by employing the Tokuyama–Mori projection operator method. The friction constant is thus shown to be renormalized by...

The experimental and the simulation results for the mean-square displacements in eight different systems (four suspensions of colloids and four molecular systems) are analyzed near their glass transitions by the mean-field theory recently proposed. The dependence of various physical quantities...

Brownian-dynamics simulations are performed on highly charged colloidal suspensions by employing an effective attractive force between colloids proposed recently by Tokuyama (Phys. Rev. E 59 (1999) R2550; Phys. Rev. E 58 (1998) R2729). In addition to a gas phase, two novel droplet phases are shown...
