Data-driven quantitative modeling of bacterial active nematics
He Li, Xia-qing Shi, Mingji Huang +5
Active matter comprises individual units that convert energy into mechanical motion. In many examples, such as bacterial systems and biofilament assays, constituent units are elong…
Self-Organized Critical Coexistence Phase in Repulsive Active Particles
Xia-qing Shi, Giordano Fausti, Hugues Chaté +2
We revisit motility-induced phase separation in two models of active particles interacting by pairwise repulsion. We show that the resulting dense phase contains gas bubbles distri…
Dynamical Sub-classes of Dry Active Nematics
Li-bing Cai, Hugues Chaté, Yu-qiang Ma +1
We show that the dominant mode of alignment plays an important role in dry active nematics,leading to two dynamical sub-classes defined by the nature of the instability of the nema…
Self-Propelled Rods: Linking Alignment-Dominated and Repulsion-Dominated Active Matter
Xia-qing Shi, Hugues Chaté
We study a robust model of self-propelled rods interacting via volume exclusion and show that its collective dynamics encompasses both that of the corresponding Vicsek-style model…
Active Matter Class with Second-Order Transition to Quasi-Long-Range Polar Order
B. Mahault, X. -c. Jiang, E. Bertin +4
We introduce and study in two dimensions a new class of dry, aligning, active matter that exhibits a direct transition to orientational order, without the phase-separation phenomen…
Fore-aft asymmetric flocking
Qiu-shi Chen, Aurelio Patelli, Hugues Chaté +2
We show that fore-aft asymmetry, a generic feature of living organisms and some active matter systems, can have a strong influence on the collective properties of even the simplest…
