Extended Data Fig. 5: Instantaneous handedness of a defect dictates its future trajectory.
a, Defect trajectories (+1/2) in active turbulence (simulations). The symbols are coloured by the associated defect-vortex regime with mirror symmetry broken with clockwise (red triangle) or anti-clockwise handedness (blue triangle), or mirror symmetric (white circles). The start point of the trajectory is represented by the green +1/2 defect symbol. b, Scatter plot of the +1/2 defect velocity and instantaneous curvature of the trajectory. Crosses (with colours of the three vortex regimes) are centred on the average curvature and velocity, with errorbars standard deviation. The negative trajectory curvature represents anti-clockwise defect dynamics, and positive for clockwise trajectories (as shown by the schematics). Curvature is shown in units of inverse active length scale ℓζ.
