Flocking by turning away
S Das, M Ciarchi, Z Zhou, J Yan, J Zhang, R Alert - Physical Review X, 2024 - APS
Flocking, as paradigmatically exemplified by birds, is the coherent collective motion of active
agents. As originally conceived, flocking emerges through alignment interactions between …

Universal Scaling of Clustering Instability for Interacting Active Brownian Particles
R Kürsten - arXiv preprint arXiv:2402.18711, 2024 - arxiv.org
We study the overdamped motion of interacting active Brownian particles in two dimensions.
An instability in the pair correlation function causes the onset of clustering. This clustering …

Circular motion subject to external alignment under active driving: Nonlinear dynamics and the circle map
AM Menzel - Physical Review E, 2022 - APS
Hardly any real self-propelling or actively driven object is perfect. Thus, undisturbed motion
will generally not follow straight lines but rather bent or circular trajectories. We here address …

Synchronized rotations of active particles on chemical substrates
Many microorganisms use chemical 'signaling'–a quintessential self-organizing strategy in
non-equilibrium–that can induce spontaneous aggregation and coordinated motion. Using …
