Figure 2: Monomer mean-square displacements of the slip-spring particle-field simulations of chain length (monomers) N = 100 (purple), N = 400 (orange) and N = 750 (brown) normalized by t^1/4. The dashed lines are the power law fits, indicating the scaling relations. The vertical dash-dotted line is the dynamical transition at entanglement time t = τ_e.
