Figure 1.

(a) MSD-s of the COM (black, simulations; red, theory) and the middle bead (green, simulations; blue, theory) in the absence of active forces. (Inset) MSD-s for the COM (same color code) when an active force of magnitude F = 200 is applied in the direction of the local normal to the polymer; L = 25 and τ = 1 were used. (b) Exponents for the MSD-s of the middle bead obtained from the analytical theory for active forces of magnitude 0.0 (black), 50.0 (red), 90.0 (green), 130.0 (blue), 170.0 (dark green), 200.0 (cyan) and 1000.0 (brown); using τ = 1.0, L = 25. The crossover time t_c (Eq. 15) for F_a = 1000.0 is denoted by the red dashed vertical line, while the burst time τ is denoted by the vertical dashed black line.
