Figure 5.

Mode-number dependence of the relaxation times of active polymers with $pL={10}^{-2}$ for the Péclet numbers $Pe={10}^1$, $3\times {10}^1$, ${10}^2$ and $5\times {10}^2$ (bottom to top). The black squares (top) show the mode-number dependence of a flexible polymer with $pL={10}^3$. The other parameters are $N={10}^3$ and $\Delta =1/3$. The solid lines indicate the relations for flexible ($\sim n^{-2}$) and semiflexible ($\sim {(2n-1)}^{-4}$) polymers, respectively. ${\tau }_1$ is the longest relaxation time.
