Inertia Drives a Flocking Phase Transition in Viscous Active Fluids
How fast must an oriented collection of extensile swimmers swim to escape the instability of viscous active suspensions? We show that the answer lies in the dimensionless combination R=ρv_{0}^{2}/2σ_{a}, where ρ is the suspension mass density, v_{0} the swim speed, and σ_{a} the active stress. Linea...
