(a) Plot of exponent $γ$ as function of the reduced light intensity $I_{0}$ for bulk system (circles) and for a single chain (squares). Inset: plots of $ln 〈 {(Δ r)}^{2} 〉$ against $ln t$ for bulk system. (b) Exemplary trajectories of CM of chains for different illumination intensity, $I_{0} = 0.85$ and $I_{0} = 0.02$ . Constant illumination, $T = 0.3$ . Based on [163].
