Phys. Rev. Lett. 80, 4915–4918 (1998)Cage Effect, Local Anisotropies, and Dynamic Heterogeneities at the Glass Transition: A Computer Study of Hard SpheresReceived 5 January 1998; published in the issue dated 1 June 1998 Computer simulations of a hard sphere system close to the glass transition are presented. From three-time correlations, we obtain information about the single-particle dynamics on all relevant time scales, including the presence of dynamic heterogeneities. A detailed picture of the cage effect in the β regime is obtained, yielding information about shape, size, and relaxation properties of the effective cage. Pronounced anisotropic dynamics is mainly observed in the β regime. © 1998 The American Physical Society URL:
