Abstract
Using simulations of hard rods in smectic-A states, we find stringlike clusters of up to 10 interlayer rods
exhibiting dynamic cooperativity. We also find non-Gaussian diffusion and heterogeneous dynamics due
to the equilibrium periodic smectic density profiles, which give rise to permanent barriers for layer-tolayer
diffusion. This relaxation behavior is surprisingly similar to that of nonequilibrium supercooled
liquids, although there the particles are trapped in transient (instead of permanent) cages.
