Abstract
We study the dynamics of a particle on an elastic surface carrying a harmonic traveling wave. The particle–surface interaction is assumed to be inelastic both normally and tangentially, and the surface is assumed to provide a kinematic boundary condition to the particle. In this setting, we search for periodic hopping solutions of the particle. The results point to a rich variety of possible particle trajectories which include periodic and chaotic motions. Interestingly, coexisting distinct multi-period attractors, (one with period-3 and its multiples, and including coexisting periodic–chaotic attractors) are observed over a frequency band. In the case of a mutually non-interacting multi-particle system, we observe ballistic and diffusive transport in inter-leaved frequency bands. These results indicate tunability of transport without/with mixing.
