# Anomalous diffusion of self-align active particle in flow background

@inproceedings{Chen2022AnomalousDO, title={Anomalous diffusion of self-align active particle in flow background}, author={Zenglei Chen and Zhibin Wu}, year={2022} }

Active particles (i.e., self-propelled particles or called microswimmers), different from passive Brownian particles, possess more complicated translational and angular dynamics, which can generate a series of anomalous transport phenomena. In this letter, we study the two-dimensional dynamics of a self-propelled pointlike particle with self-aligning property moving in Poiseuille flow. The results show the effective anomalous diffusion coefficient changes sharply with the change of temperature…

It is proved that ratcheting of Janus particles can be orders of magnitude stronger than for ordinary thermal potential ratchets and thus experimentally accessible and in particular, autonomous pumping of a large mixture of passive particles can been induced by just adding a small fraction of JanUS particles.

It is shown that self-alignment, taking the form of a torque coupling the particle orientation and velocity, is responsible for the emergence of this second dynamical state for which the particle condensates at a finite distance from the trap center.
