Lifetime of dynamic heterogeneities in a binary Lennard-Jones mixture
Elijah Flenner, Grzegorz Szamel
A four-time correlation function was calculated using a computer simulation of a binary Lennard-Jones mixture. The information content of the four-time correlation function is simi…
Is a "homogeneous" description of dynamic heterogeneities possible?
Grzegorz Szamel
We study the simplest model of dynamic heterogeneities in glass forming liquids: one-spin facilitated kinetic Ising model introduced by Fredrickson and Andersen [G.H. Fredrickson a…
Independence of the relaxation of a supercooled fluid of its microscopic dynamics: need for yet another extension of the mode-coupling theory
Grzegorz Szamel, Elijah Flenner
Using Brownian Dynamics computer simulations we show that the relaxation of a supercooled Brownian system is qualitatively the same as that of a Newtonian system. In particular, ne…
Self-diffusion in sheared colloidal suspensions: violation of fluctuation-dissipation relation
Grzegorz Szamel
Using memory-function formalism we show that in sheared colloidal suspensions the fluctuation-dissipation theorem for self-diffusion, i.e. Einstein's relation between self-diffusio…
Gaussian density fluctuations, mode coupling theory, and all that
Grzegorz Szamel
We consider a toy model for glassy dynamics of colloidal suspensions: a single Brownian particle diffusing among immobile obstacles. If Gaussian factorization of static density flu…
