Large-Scale Chaos and Fluctuations in Active Nematics
Large-Scale Chaos and Fluctuations in Active Nematics
We show that dry active nematics, e.g., collections of shaken elongated granular particles, exhibit large-scale spatiotemporal chaos made of interacting dense, ordered, bandlike structures in a parameter region including the linear onset of nematic order. These results are obtained from the study of both the well-known (deterministic) hydrodynamic equations describing …
