Composite search of active particles in three-dimensional space based on non-directional cues
Justus A. Kromer, Andrea Auconi, Benjamin M. Friedrich
We theoretically address minimal search strategies of active, self-propelled particles towards hidden targets in three-dimensional space. The particles can sense if a target is clo…

Chemokinetic scattering, trapping, and avoidance of active Brownian particles
Justus A. Kromer, Noelia de la Cruz, Benjamin M. Friedrich
We present a theory of chemokinetic search agents that regulate directional fluctuations according to distance from a target. A dynamic scattering effect reduces the probability to…

Variability of collective dynamics in random tree networks of strongly-coupled stochastic excitable elements
Ali Khaledi-Nasab, Justus A. Kromer, Lutz Schimansky-Geier +1
We study the collective dynamics of strongly diffusively coupled excitable elements on small random tree networks. Stochastic external inputs are applied to the leaves causing larg…
