Persistent cell movement enhances synchronization in the absence of spatial velocity correlations. (A) Time evolution of average phase order parameter 〈Z(t)〉 for different values of polarity noise intensities Dφ. Error bars indicate the SD. (B) Velocity autocorrelation Ca(t) defined by Eq. 7 for different values of Dφ. (C) Time evolution of m(t) for different values of Dφ. In all panels, L = 24, N = 800, v0 = 1.2, μ = 10, κφ = 0, ω = 2.1, and Dθ = 0.1 in Eqs. 1–5. To see this figure in color, go online.
