(A) Evolution of P(V) and its cumulative distribution for different levels of attraction. Notice that V is rescaled by the volume of the average particle for each distribution. The distributions shift to larger volumes as a function of attraction. The data are fit with the shifted Γ distribution in Eq. 1 and compared to the monodisperse case. (B) Data collapse is observed when V is rescaled by the shifted average volume of the cell 〈V〉-Vmin. This rescaling implies that the shape parameter k remains constant with attraction. The inset shows that the compactivity χ decreases with increasing density ϕ, which is consistent with the observed decrease in 〈V〉. The RCP point curiously does not have the lowest compactivity.
