Mixing of four chains in a large confinement volume (corresponding to a small volume fraction of beads, ϕ = 0.001) while varying bead-bead interactions, ϵ.

(a) Simulation snapshots show the mixing of four chains mixing as a function of interaction strength, ϵ, for persistence lengths l_p = 1 bead and l_p = 5 beads. Note that some snapshots were zoomed out because they were too large and would take up too much space if they were shown at their actual size. (b) The radius of gyration as a function of ϵ for l_p = 1 bead (gray color) and l_p = 5 beads (black color). Note that the attraction strength at which collapse occurs for the one-bead persistence length is ϵ_c = 0.3, whereas for the 5-beads persistence length, ϵ_c = 0.4.
