(A) The radial distribution function g(r) for a polymer liquid (ε = 1, 1000-mer), a polymer glass (ε = 10, 1000-mer) and a colloidal crystal (ε = 10, free particles). (B) The self part and (C) the distinct part of the van Hove correlation function plotted for different interaction strengths ε for a full 1000-mer chain. Values are calculated for the interval between 0.09τ and 100τ after the reference time of t = 3 × 105τ, when the glassy states are fully established. (D) The FWHM w(t) of the self van Hove correlation function plotted as a function of time for a range of interaction strengths ε. Averages were calculated at increasing time after the reference t = 3 × 105τ. Smaller time steps, 0.001τ were used here for higher resolution.
