Probing the Equilibrium Dynamics of Colloidal Hard Spheres above the Mode-Coupling Glass Transition
Probing the Equilibrium Dynamics of Colloidal Hard Spheres above the Mode-Coupling Glass Transition
We use dynamic light scattering and computer simulations to study equilibrium dynamics and dynamic heterogeneity in concentrated suspensions of colloidal hard spheres. Our study covers an unprecedented density range and spans seven decades in structural relaxation time, tau(alpha0, including equilibrium measurements above phi(c), the location of the glass transition deduced …
