Reaction Delays Boost, Rectify, and Reverse Motility in Activity Landscapes
Constantin Rein, Klaus Kroy, Viktor Holubec
Local detailed balance restricts transport by self-propulsion in static activity landscapes. We show that a delayed speed adaptation (``delayed motility/kinesis'') generically brea…
Cohesion from Action-Dependent Perception in Decision-Based Active Matter
Julian Giraldo-Barreto, Viktor Holubec
Many biological and artificial agents reorient by locally optimizing a utility over a finite set of candidate actions. We show that decision rules based on pairwise additive scores…
Feedback control and delayed interactions in active matter
Viktor Holubec, Frank Cichos
Feedback control plays a central role in active matter, yet it is inevitably accompanied by noise and finite perception--action delays. This Perspective reviews recent advances on…
Programmable Hydrodynamics of Active Particles
Lisa Rohde, Gordei Anchutkin, Viktor Holubec +1
Self-propelled microparticles create flow fields that determine how they interact with surfaces, external flows, and each other. These flow fields fall into distinct classes--pushe…
Delayed Active Swimmer in a Velocity Landscape
Viktor Holubec, Alexander Fischer, Giovanni Volpe +1
Self-propelled active particles exhibit delayed responses to environmental changes, modulating their propulsion speed through intrinsic sensing and feedback mechanisms. This adapti…
Active Matter Flocking via Predictive Alignment
Julian Giraldo-Barreto, Viktor Holubec
Understanding collective self-organization in active matter, such as bird flocks and fish schools, remains a grand challenge in physics. Interactions that induce alignment are esse…
