Figure 8: D$_{eff}$ computed with Langevin dynamics simulations. The Langevin dynamics simulations are performed with various prefactors A = αk$_{B}$TR 3 $_{1}$, where k$_{B}$T = 1 , and the values of α are given in the legend. 0 5 10 15 k$_{c}$R$^{2}$$_{2}$/ D$_{1}$ 1 1.2 1.4 1.6 1.8 D eff / D 1 =0.1 =0.2 =0.3 28
