Emergent smectic order in simple active particle models
Pawel Romanczuk, Hugues Chaté, Leiming Chen +2
Novel "smectic-P" behavior, in which self-propelled particles form rows and move on average along them, occurs generically within the orientationally-ordered phase of simple models…
Large-scale chaos and fluctuations in active nematics
Sandrine Ngo, Anton Peshkov, Igor S. Aranson +3
We show that "dry" active nematics, e.g. collections of shaken elongated granular particles, exhibit large-scale spatiotemporal chaos made of interacting dense, ordered, band-like…
Swarming, Schooling, Milling: Phase diagram of a data-driven fish school model
Daniel S. Calovi, Ugo Lopez, Sandrine Ngo +3
We determine the basic phase diagram of the fish school model derived from data by Gautrais etal (PLoS Comp. Biol. 8, e1002678 (2012)), exploring its parameter space beyond the par…
Competing ferromagnetic and nematic alignment in self-propelled polar particles
Sandrine Ngo, Francesco Ginelli, Hugues Chaté
We study a Vicsek-style model of self-propelled particles where ferromagnetic and nematic alignment compete in both the usual "metric" version and in the "metric-free" case where a…
Continuous theory of active matter systems with metric-free interactions
Anton Peshkov, Sandrine Ngo, Eric Bertin +2
We derive a hydrodynamic description of metric-free active matter: starting from self-propelled particles aligning with neighbors defined by "topological" rules, not metric zones,…
