Brownian transport of self-propelled overdamped microswimmers (like Janus particles) in a two-dimensional periodically compartmentalized channel is numerically investigated for different compartment geometries, boundary collisional dynamics, and particle rotational diffusion. The resulting time-correlated active Brownian motion is subject to rectification in the presence of spatial asymmetry. We prove that ratcheting of Janus particles can be orders of magnitude stronger than for ordinary…

Rectification of self-propelled particles in entropic barriers: finite size effects
Transport of finite size self-propelled particles is numerically investigated in a two-dimensional channel. Because of the existence of the self-propelled speed, the self-propelled particles exhibit
Entropic stochastic resonance of a self-propelled Janus particle
Entropic stochastic resonance is investigated when a self-propelled Janus particle moves in a double-cavity container. Numerical simulation results indicate the entropic stochastic resonance can

TLDR
The mean exit time of elliptic Janus particles from narrow two-dimensional cavities with reflecting walls is found to be a minimum when the self-propulsion length is equal to the cavity size and the optimum mean escape time is found as a function of theSelfpropulsion velocity, translational diffusion, and particle shape.
Response of active Brownian particles to boundary driving.
TLDR
Underdamped active Brownian particles in a sheared channel geometry observe counterintuitive phenomena stemming from the interplay of activity, interparticle interactions, and the boundary driving, including a flow reversal near the wall and an induced polarization of the particle self-propulsion directions.
Entropic ratchet transport of interacting active Brownian particles.
TLDR
It is found that the interaction between active particles can greatly affect the ratchet transport and, for the strong interaction, the average velocity is independent of the interaction.
Transport of underdamped active particles in ratchet potentials.
TLDR
It is found that the ratchet effect of active noninteracting particles occurs in a single direction in the overdamped limit, and by suitably tailoring the parameters, underdamped active particles with different self-propulsion forces can move in different directions and can be separated.
