Mapping from a fragile glass-forming system to a simpler one near their glass transitions

Tokuyama, Michio; Narumi, Takayuki; Kohira, Eri - In: Physica A: Statistical Mechanics and its Applications 385 (2007) 2, pp. 439-455

collapsed on a master curve given by MFT when DSL(φ)=DSL(T), where DSL is a long-time self-diffusion coefficient. We also …

Universal effects of collective interactions on long-time self-diffusion coefficients in hard-sphere systems

Tokuyama, Michio; Yamazaki, Hiroyuki; Terada, Yayoi - In: Physica A: Statistical Mechanics and its Applications 328 (2003) 3, pp. 367-379

We investigate how universal the collective behavior, due to the many-body interactions in polydisperse hard-sphere systems, is at higher volume fractions. We perform two types of computer simulations, a Brownian-dynamics simulation on colloidal suspensions of hard spheres, where the...
