Kramers escape of a self-propelled particle
Alexander Geiseler, Peter Hänggi, Gerhard Schmid
We investigate the escape rate of an overdamped, self-propelled spherical Brownian particle on a surface from a metastable potential well. Within a modeling in terms of a 1D consta…
Diffusion of Chiral Janus Particles in a Sinusoidal Channel
Xue Ao, Pulak Kumar Ghosh, Yunyun Li +3
We investigate the transport diffusivity of artificial microswimmers, a.k.a. Janus particles, moving in a sinusoidal channel in the absence of external biases. Their diffusion cons…
Active Brownian motion in a narrow channel
Xue Ao, Pulak Kumar Ghosh, Yunyun Li +3
We review recent advances in rectification control of artificial microswimmers, also known as Janus particles, diffusing along narrow, periodically corrugated channels. The swimmer…
Giant enhancement of hydrodynamically enforced entropic trapping in thin channels
S. Martens, A. V. Straube, G. Schmid +2
Using our generalized Fick-Jacobs approach [Martens et al., PRL 110, 010601 (2013); Martens et al., Eur. Phys. J. Spec. Topics 222, 2453-2463 (2013)] and extensive Brownian dynamic…
Optimizing the Performance of the Entropic Splitter for Particle Separation
Thomas Motz, Gerhard Schmid, Peter Hänggi +2
Recently, it has been shown that entropy can be used to sort Brownian particles according to their size. In particular, a combination of a static and a time-dependent force applied…
How entropy and hydrodynamics cooperate in rectifying particle transport
S. Martens, G. Schmid, A. V. Straube +2
Using the analytical Fick-Jacobs approximation formalism and extensive Brownian dynamics simulations we study particle transport through two-dimensional periodic channels with tria…
