Diffusion properties of active particles with directional reversal
Robert Großmann, Fernando Peruani, Markus Bär
The diffusion properties of self-propelled particles which move at constant speed and, in addition, reverse their direction of motion repeatedly are investigated. The internal dyna…
Hydrodynamic length-scale selection and effective viscosity in microswimmer suspensions
Sebastian Heidenreich, Jörn Dunkel, Sabine H. L. Klapp +1
A universal characteristic of mesoscale turbulence in active suspensions is the emergence of a typical vortex length scale, distinctly different from the scale-invariance of turbul…
Superdiffusion, large-scale synchronization and topological defects
Robert Großmann, Fernando Peruani, Markus Bär
We study an ensemble of random walkers carrying internal noisy phase oscillators which are synchronized among the walkers by local interactions. Due to individual mobility, the int…
Pattern formation in active particle systems due to competing alignment interactions
Robert Großmann, Pawel Romanczuk, Markus Bär +1
Recently, we proposed a self-propelled particle model with competing alignment interactions: nearby particles tend to align their velocities whereas they anti-align their direction…
A geometric approach to self-propelled motion in isotropic and anisotropic environments
Robert Großmann, Fernando Peruani, Markus Bär
We propose a geometric perspective to describe the motion of self-propelled particles moving at constant speed in d dimensions. We exploit the fact that the vector that conveys the…
