    "abstract": "We investigate the dynamics of a dimer bouncing on a vertically oscillated\nplate. The dimer, composed of two spheres rigidly connected by a light rod,\nexhibits several modes depending on initial and driving conditions. The first\nexcited mode has a novel horizontal drift in which one end of the dimer stays\non the plate during most of the cycle, while the other end bounces in phase\nwith the plate. The speed and direction of the drift depend on the aspect ratio\nof the dimer. We employ event-driven simulations based on a detailed treatment\nof frictional interactions between the dimer and the plate in order to\nelucidate the nature of the transport mechanism in the drift mode.",
