Kurzfassung
The wake-mediated propulsion of an 'extra' particle in a channel of two neighboring rows of a two-dimensional plasma crystal, observed experimentally by Du et al. Phys. Rev. E 89, 021101(R) (2014), is explained in simulations and theory. We use the simple model of a pointlike ion wake charge to reproduce this intriguing effect in simulations, allowing for a detailed investigation and a deeper understanding of the underlying dynamics. We show that the nonreciprocity of the particle interaction, owing to the wake charges, is responsible for a broken symmetry of the channel that enables a persistent self-propelled motion of the extra particle. We find good agreement of the terminal extra-particle velocity with our theoretical considerations and with experiments.
