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…
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,…
A generic coupling between internal states and activity leads to activation fronts and criticality in active systems
Hadrien-Matthieu Gascuel, Parisa Rahmani, Richard Bon +1
To understand the onset of collective motion, we investigate active systems where particles switch on and off their self-propulsion. We prove that even when the only possible trans…
Kinetic and macroscopic models for active particles exploring complex environments with an internal navigation control system
L. Gómez-Nava, T. Goudon, F. Peruani
A large number of biological systems - from bacteria to sheep - can be described as ensembles of self-propelled agents (active particles) with a complex internal dynamic that contr…
