Summary

This paper studied the clustering and dynamical states of small stainless steel spheres when they were vibrated in fluid. The long-range attractive interaction and short-range repulsive interaction between particles are fluid mediated. The resulting patterns include hexagonally ordered microcrystallites, time-periodic structures, and chaotic fluctuating patterns with complex dynamics.
