Minority-Triggered Reorientations Yield Macroscopic Cascades and Enhanced Responsiveness in Swarms
Simon Syga, Chandraniva Guha Ray, Josué Manik Nava-Sedeño +2
Collective motion in animals and cells often exhibits rapid reorientations and scale-free velocity correlations. This allows information to spread rapidly through the group, allowi…
Collective behavior based on agent-environment interactions
Gaston Briozzo, Gustavo J. Sibona, Fernando Peruani
We present a model of active particles interacting through a dynamic, heterogeneous environment, leading to emergent collective behaviors without direct agent-to-agent communicatio…
Spreading processes on heterogeneous active systems: spreading threshold, immunization strategies, and vaccination noise
Benjamín Marcolongo, Gustavo J. Sibona, Fernando Peruani
We study spreading processes in two-dimensional systems of heterogeneous active agents that exhibit different individual active speeds. We obtain, combining kinetic and complex net…
Resource and population dynamics in an agent-environment interaction model
G. Briozzo, G. J. Sibona, F. Peruani
In any ecosystem, the conditions of the environment and the characteristics of the species that inhabit it are entangled, co-evolving in space and time. We introduce a model that c…
Zoology of collective patterns modulated by non-reciprocal, long-range interactions
Edgardo Brigatti, Fernando Peruani
We investigate active particles that exhibit long-range interactions only restricted by a field of view, which is characterized by an angle . We show that constraining attractiv…
Confinement controls bacterial spreading at all scales
Renaud Baillou, Marta Pedrosa Garcia-Moreno, Quentin Guigue +5
Navigation of microorganisms is controlled by internal processes ultimately sensitive to mechanical or chemical signaling encountered along the path. In many natural environments,…
