Fluctuation-Induced First Order Transition to Collective Motion
David Martin, Gianmarco Spera, Hugues Chaté +4
The nature of the transition to collective motion in assemblies of aligning self-propelled particles remains a long-standing matter of debate. In this article, we focus on dry acti…
Metastability of Discrete-Symmetry Flocks
Brieuc Benvegnen, Omer Granek, Sunghan Ro +6
We study the stability of the ordered phase of flocking models with a scalar order parameter. Using both the active Ising model and a hydrodynamic description, we show that droplet…
Rheology of active fluids
Alfredo Lanzaro, Luigi Gentile
This chapter on the rheology of active fluids is an attempt to correlate theoretical and experimental work. A considerable amount of theoretical work and most of the experimental d…
Characterization and Control of the Run-and-Tumble Dynamics of {\it Escherichia Coli}
Christina Kurzthaler, Yongfeng Zhao, Nan Zhou +8
We characterize the full spatiotemporal gait of populations of swimming {\it Escherichia coli} using renewal processes to analyze the measurements of intermediate scattering functi…
Quantitative characterization of run-and-tumble statistics in bulk bacterial suspensions
Yongfeng Zhao, Christina Kurzthaler, Nan Zhou +8
We introduce a numerical method to extract the parameters of run-and-tumble dynamics from experimental measurements of the intermediate scattering function. We show that proceeding…
Flocking in One Dimension: Asters and Reversals
Brieuc Benvegnen, Hugues Chaté, Pavel Krapivsky +2
We study the one-dimensional active Ising model in which aligning particles undergo diffusion biased by the signs of their spins. The phase diagram obtained varying the density of…
