These two videos show particle dynamics in small-scale simulations of a distinguishable-particle lattice model (DPLM) on a 40x40 lattice with 1592 particles (randomly colored) and 8 voids (white) at T=0.5 for a simulation duration of 0.006 and at T=0.16 for a duration of 41400. For T = 0.5, voids diffuse independently without trapping. For T=0.16, isolated voids are trapped by the disorder. Two coupled voids on the top right corner move substantially more vigorously demonstrating dynamic facilitation.
