Time-dependent dynamics in the confined lattice Lorentz gas
A. Squarcini, A. Tinti, P. Illien +2
We study a lattice model describing the non-equilibrium dynamics emerging from the pulling of a tracer particle through a disordered medium occupied by randomly placed obstacles. T…
Dimensional crossover via confinement in the lattice Lorentz gas
A. Squarcini, A. Tinti, P. Illien +2
We consider a lattice model in which a tracer particle moves in the presence of randomly distributed immobile obstacles. The crowding effect due to the obstacles interplays with th…
Intermediate scattering function of a gravitactic circle swimmer
Regina Rusch, Oleksandr Chepizhko, Thomas Franosch
We analyze gravitaxis of a Brownian circle swimmer by deriving and characterizing analytically the experimentally measurable intermediate scattering function (ISF). To solve the as…
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…
Relating thermodynamic quantities of convex-hard-body fluids to the body's shape
Thomas Franosch, Cristiano De Michele, Rolf Schilling
For a fluid of convex hard particles, characterized by a length scale and an anisotropy parameter , we develop a formalism allowing one to relate thermodynamic…
First-passage-time statistics of active Brownian particles: A perturbative approach
Yanis Baouche, Magali Le Goff, Christina Kurzthaler +1
We study the first-passage-time (FPT) properties of active Brownian particles to reach an absorbing wall in two dimensions. Employing a perturbation approach we obtain exact analyt…
