Fig. 3: Change in shape of CRRs on approaching the MCT crossover.
a, b Particle displacement map over the cage-breaking time t* for Γ = 22 and Γ = 63, respectively. Here colors represent overlap values with red representing high particle overlap over t* and blue representing poor overlaps indicating particles having made hop. c Average cluster size 〈Nc〉 verses Γ (red open circles), 〈Nc〉 shows a maximum at mode-coupling crossover ΓMCT(vertical black dash-dot line). d Distribution of the number of fast nearest-neighbors for a mobile particle, P(NN), for Γ = 22 (black squares), Γ = 30 (magenta triangles), Γ = 53 (olive green squares), Γ = 63 (violet triangles), and Γ = 101 (wine stars). The peak of P(NN) shifts from NN = 2 to NN = 3 indicating that dynamical heterogeneities becoming more compact with increasing Γ. e Representative dynamical heterogeneities of 12-particle clusters for Γ = 30, 53, and 63. Particles that comprise the core of dynamical heterogeneities are shown in red while the stringy particles are shown in blue.
