Single-Particle Dynamics in Dense Granular Fluids under Driving
  We present a mode-coupling theory for the dynamics of a tagged particle in a driven granular fluid close to the glass transition. The mean-squared displacement is shown to exhibit a plateau indicating structural arrest. In contrast to elastic hard-sphere fluids, which are solely controlled by volume fraction, the localisation length as well as the critical dynamics depend on the degree of dissipation, parametrized by the coefficient of normal restitution epsilon. Hence the resulting glassy structure as well as the critical dynamics are nonuniversal with respect to epsilon.
