Dynamics of an active agent subject to orientational resetting — •Yanis Baouche and Christina Kurzthaler — Max Planck Institute for the Physics of Complex Systems, Dresden, Germany

We study the dynamics of an active particle whose swimming direction is subject to rotational diffusion and a stochastic resetting mechanism. The latter allows for taking into account the particle's response to external stimuli.

We use renewal processes to model the reorientation mechanism of the active agent and provide analytical expressions for the characteristic function of the stochastic process and its low-order moments.

Finally, the interplay between rotational diffusion and resetting of the particle's orientation is quantified for different resetting distributions.
