Squirming motion near corrugated surfaces
Sagnik Garai, Thomas G. Fai, Christina Kurzthaler
Swimming microorganisms often operate in complex confinement, where an interplay of long-ranged hydrodynamic interactions and a short-ranged repulsive interaction can give rise to…
Disorder-induced persistent random motion and trapping of microswimmers
Mirko Residori, Sebastian Aland, Christina Kurzthaler
Microorganisms ofter move in confined, disordered environments, where hydrodynamic couplings can modify their transport behavior. Using extensive finite-element simulations, we inv…
Active Brownian Dynamics in Channels: First-Passage and Spatiotemporal Properties via Siegmund Duality
Yanis Baouche, Mathis Guéneau, Mathis Guéneau +1
Accumulation at boundaries represents a widely observed phenomenon in active systems with implications for microbial ecology and engineering applications. To rationalize the underl…
Vorticity-induced surfing and trapping in porous media
Pallabi Das, Mirko Residori, Axel Voigt +2
Microorganisms often encounter strong confinement and complex hydrodynamic flows while navigating their habitats. Combining finite-element methods and stochastic simulations, we st…
Hydrodynamic Attraction and Hindered Diffusion Govern First-passage Times of Swimming Microorganisms
Yanis Baouche, Magali Le Goff, Thomas Franosch +1
The motion of microorganisms in their natural habitat is strongly influenced by their propulsion mechanisms, geometrical constraints, and random fluctuations. Here, we study numeri…
Optimal first-passage times of active Brownian particles under stochastic resetting
Yanis Baouche, Christina Kurzthaler
We study the first-passage-time (FPT) properties of an active Brownian particle under stochastic resetting to its initial configuration, comprising its position and orientation, to…
