Time-dependent active microrheology in dilute colloidal suspensions
Sebastian Leitmann, Suvendu Mandal, Matthias Fuchs +2
In a microrheological set-up a single probe particle immersed in a complex fluid is exposed to a strong external force driving the system out of equilibrium. Here, we elaborate ana…
Time-dependent perpendicular fluctuations in the driven lattice Lorentz gas
Sebastian Leitmann, Thomas Schwab, Thomas Franosch
We present results for the fluctuations of the displacement of a tracer particle on a planar lattice pulled by a step force in the presence of impenetrable, immobile obstacles. The…
Dynamically Crowded Solutions of Infinitely Thin Brownian Needles
Sebastian Leitmann, Felix Höfling, Thomas Franosch
We study the dynamics of solutions of infinitely thin needles up to densities deep in the semidilute regime by Brownian dynamics simulations. For high densities, these solutions be…
Intermediate scattering function of an anisotropic active Brownian particle
Christina Kurzthaler, Sebastian Leitmann, Thomas Franosch
Various challenges are faced when animalcules such as bacteria, protozoa, algae, or sperms move autonomously in aqueous media at low Reynolds number. These active agents are subjec…
Time-Dependent Fluctuations and Superdiffusivity in the Driven Lattice Lorentz Gas
Sebastian Leitmann, Thomas Franosch
We consider a tracer particle on a lattice in the presence of immobile obstacles. Starting from equilibrium, a force pulling on the particle is switched on, driving the system to a…
Tube Concept for Entangled Stiff Fibers Predicts Their Dynamics in Space and Time
Sebastian Leitmann, Felix Höfling, Thomas Franosch
We study dynamically crowded solutions of stiff fibers deep in the semidilute regime, where the motion of a single constituent becomes increasingly confined to a narrow tube. The s…
Nonlinear Response in the Driven Lattice Lorentz Gas
Sebastian Leitmann, Thomas Franosch
We determine the nonlinear time-dependent response of a tracer on a lattice with randomly distributed hard obstacles as a force is switched on. The calculation is exact to first or…
