Collective motion of active Brownian particles in one dimension
Pawel Romanczuk, Udo Erdmann
We analyze a model of active Brownian particles with non-linear friction and velocity coupling in one spatial dimension. The model exhibits two modes of motion observed in biologic…
On the attractors of two-dimensional Rayleigh oscillators including noise
Udo Erdmann, Werner Ebeling
We study sustained oscillations in two-dimensional oscillator systems driven by Rayleigh-type negative friction. In particular we investigate the influence of mismatch of the two f…
Noise-Induced Transition from Translational to Rotational Motion of Swarms
Udo Erdmann, Werner Ebeling, Alexander S. Mikhailov
We consider a model of active Brownian agents interacting via a harmonic attractive potential in a two-dimensional system in the presence of noise. By numerical simulations, we sho…
Advantages of Hopping on a Zig-zag Course
Lutz Schimansky-Geier, Udo Erdmann, Niko Komin
We investigate self-moving particles which prefer to hop with a certain turning angle equally distributed to the right or left. We assume this turning angle distribution to be give…
Active Brownian Particle and Random Walk Theories of the Motions of Zooplankton: Application to Experiments with Swarms of Daphnia
Udo Erdmann, Werner Ebeling, Lutz Schimansky-Geier +2
Active Brownian Particles are self-propelled particles that move in a dissipative medium subject to random forces, or noise . Additionally, they can be confined by an external fiel…
Nonequilibrium statistical mechanics of swarms of driven particles
Werner Ebeling, Udo Erdmann
As a rough model for the collective motions of cells and organisms we develop here the statistical mechanics of swarms of self-propelled particles. Our approach is closely related…
