Fig. 1.

Currently accepted state diagram of hard spheres with short-range square-well attraction (depth u₀ normalized to the thermal energy, k_BT) at high volume fraction (ϕ), showing three distinct states: ergodic fluid (EF), repulsive glass (RG) and attractive glass (AG). The distinction between RG and AG ends at the so-called A₃ point. The boundaries shown have been previously determined (24) for the same system of “sticky bidisperse hard spheres” as investigated in this work (see Materials and Methods for details).
