| Zusammenfassung | The diffusion properties of self-propelled particles which move at constant speed and, in addition, reverse their direction of motion repeatedly are investigated. The internal dynamics of particles triggering these reversal processes is modeled by a stochastic clock. The velocity correlation function as well as the mean squared displacement is investigated and, furthermore, a general expression for the diffusion coefficient for self-propelled particles with directional reversal is derived. Our Analysis reveals the existence of an optimal, finite rotational noise amplitude which maximizes the diffusion coefficient.Wecomment on the relevance of these results with regard to biological systems and suggest further experiments in this context. |
