Numerical and theoretical study of a monodisperse hard-sphere glass former.
Abstract
There exists a variety of theories of the glass transition and many more numerical
models. But because the models need built-in complexity to prevent crystallization,
comparisons with theory can be difficult. We study the dynamics of a deeply supersaturated
monodisperse four-dimensional (4D) hard-sphere fluid, which has no such complexity,
but whose strong intrinsic geometrical frustration inhibits crystallization, even
when deeply supersaturated. As an application, we compare its behavior to the mode-coupling
theory (MCT) of glass formation. We find MCT to describe this system better than any
other structural glass formers in lower dimensions. The reduction in dynamical heterogeneity
in 4D suggested by a milder violation of the Stokes-Einstein relation could explain
the agreement. These results are consistent with a mean-field scenario of the glass
transition.
