Swimming path statistics of an active Brownian particle with time-dependent self-propulsion
Sonja Babel, Borge ten Hagen, Hartmut Löwen
Typically, in the description of active Brownian particles, a constant effective propulsion force is assumed, which is then subjected to fluctuations in orientation and translation…
Two-dimensional colloidal mixtures in magnetic and gravitational fields
Hartmut Löwen, Tobias Horn, Tim Neuhaus +1
This mini-review is concerned with two-dimensional colloidal mixtures exposed to various kinds of external fields. By a magnetic field perpendicular to the plane, dipole moments ar…
Non-Gaussian statistics for the motion of self-propelled Janus particles: experiment versus theory
Xu Zheng, Borge ten Hagen, Andreas Kaiser +4
Spherical Janus particles are one of the most prominent examples for active Brownian objects. Here, we study the diffusiophoretic motion of such microswimmers in experiment and in…
Dynamics of a deformable active particle under shear flow
Mitsusuke Tarama, Andreas M. Menzel, Borge ten Hagen +3
The motion of a deformable active particle in linear shear flow is explored theoretically. Based on symmetry considerations, in two spatial dimensions, we propose coupled nonlinear…
Brownian motion and the hydrodynamic friction tensor for colloidal particles of complex shape
Daniela J. Kraft, Raphael Wittkowski, Borge ten Hagen +3
We synthesize colloidal particles with various anisotropic shapes and track their orientationally resolved Brownian trajectories using confocal microscopy. An analysis of appropria…
Circular motion of asymmetric self-propelling particles
Felix Kümmel, Borge ten Hagen, Raphael Wittkowski +5
Micron-sized self-propelled (active) particles can be considered as model systems for characterizing more complex biological organisms like swimming bacteria or motile cells. We pr…
