| contents | A layer of monodisperse circular steel disks in a nearly square horizontal cell forms, for shear amplitudes SA $\le$ 0.08, hexagonal close-packed crystallites that grow and merge until a single crystal fills the container. Increasing the shear amplitude leads to another reproducible regime, 0.21 $\le$ SA $\le$ 0.27, where a few large polycrystallites grow, shrink, and rotate with shear cycling, but do not evolve into a single crystal that fills the container. These results are robust within certain ranges of applied pressure and shear frequency. |
