From: Discontinuous nature of the repulsive-to-attractive colloidal glass transition
(a) Non-gaussian parameter α2(Δt) for the repulsive glass (U = 0 kBT, circles), the supercooled liquid (U = 2.5 KBT, triangles) and attractive glass (U = 8.3 kBT, squares), (b–d) show corresponding particles displacement probabilities P(Δr, Δt) for Δt = 0.5 s (circles) and t = t* (squares). Lines are fits to Gaussian (blue) and exponential distributions (red and black) as discussed in the text.
