Fig. 6: Run-and-tumble polymers in a dilute environment.
From: A geometric criterion for the optimal spreading of active polymers in porous media
Sketch of the a run-and-tumble motion and b tumbling mechanism of a stiff polymer. Here, the unit vectors \({{{{{{{{\bf{n}}}}}}}}}_{0,1}^{(1)}\) and \({{{{{{{{\bf{n}}}}}}}}}_{0,1}^{(2)}\) span the plane normal to the tangent t0,1. The normal vector n0,1 lies in this plane. c Trajectories of three run-and-tumble polymers (solid lines) and run-reverse polymers (dotted lines) with vanishing translational diffusivity, D0 = 0, and run-length ℓrun/σ = 20.
