We perform molecular dynamics simulations for a slightly polydisperse, densely packed hard-sphere fluid confined between two parallel walls . The diffusion coefficient parallel to the walls is observed to vary by orders of magnitudes upon changing the wall separation while keeping the packing fraction fixed. A striking multiple reentrance scenario emerges for the transition from liquid to glass as the wall separation becomes comparable to the particle diameter. The non-monotonic behavior of the phase diagram is rationalized in terms of a numerical solution of a recently developed mode-coupling theory [1,2].
