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…

Fluctuation-response theorem for Kullback-Leibler divergences to quantify causation
Andrea Auconi, Benjamin M. Friedrich, Andrea Giansanti
We define a new measure of causation from a fluctuation-response theorem for Kullback-Leibler divergences, based on the information-theoretic cost of perturbations. This informatio…
