Memory effects and active Brownian diffusion
Pulak K. Ghosh, Yunyun Li, Giampiero Marchegiani +1
A self-propelled artificial microswimmer is often modeled as a ballistic Brownian particle moving with constant speed aligned along one of its axis, but changing direction due to r…
Pseudo-Chemotactic Drifts of Artificial Microswimmers
Pulak K. Ghosh, Yunyun Li, Fabio Marchesoni +1
We numerically investigate the motion of active artificial microswimmers diffusing in a fuel concentration gradient. We observe that, in the steady state, their probability density…
Interacting single-file system: Fractional Langevin formulation versus diffusion-noise approach
Alessandro Taloni, Fabio Marchesoni
We review the latest advances in the analytical modelling of single file diffusion. We focus first on the derivation of the fractional Langevin equation that describes the motion o…
