Analysis of aligning active local searchers orbiting around their common home position
J. Noetel, L. Schimansky-Geier
We discuss effects of pairwise aligning interactions in an ensemble of central place foragers or of searchers that are connected to a common home. In a wider sense, we also conside…
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…
Cooperative surmounting of bottlenecks
D. Hennig, C. Mulhern, L. Schimansky-Geier +2
The physics of activated escape of objects out of a metastable state plays a key role in diverse scientific areas involving chemical kinetics, diffusion and dislocation motion in s…
Nonlinear response of a linear chain to weak driving
D. Hennig, C. Mulhern, A. D. Burbanks +1
We study the escape of a chain of coupled units over the barrier of a metastable potential. It is demonstrated that a very weak external driving field with suitably chosen frequenc…
Excitable elements controlled by noise and network structure
Bernard Sonnenschein, Michael A. Zaks, Alexander B. Neiman +1
We study collective dynamics of complex networks of stochastic excitable elements, active rotators. In the thermodynamic limit of infinite number of elements, we apply a mean-field…
How entropy and hydrodynamics cooperate in rectifying particle transport
S. Martens, G. Schmid, A. V. Straube +2
Using the analytical Fick-Jacobs approximation formalism and extensive Brownian dynamics simulations we study particle transport through two-dimensional periodic channels with tria…
