We study a strongly interacting dense hard-sphere system confined between twoparallel plates by event-driven molecular dynamics simulations to address thefundamental question of the nature of the 3D to 2D crossover. As the fluidbecomes more and more confined the dynamics of the transverse and lateraldegrees of freedom decouple, which is accompanied by a diverging time scaleseparating 2D from 3D behavior. Relying on the time-correlation function of thetransversal kinetic energy the scaling behavior and its density-dependence isexplored. Surprisingly, our simulations reveal that its time-dependence becomespurely exponential such that memory effects can be ignored. We rationalize ourfindings quantitatively in terms of an analytic theory which becomes exact inthe limit of strong confinement.
