Our experimental results for the Lindemann melting criterion, the radial distribution function, the bond order parameter, and the statistics of topological changes at the particle level are the same as those found in simulations of equilibrium hard disks. This direct mapping suggests that the study of equilibrium systems can be effectively applied to study nonequilibrium steady states such as those found in our driven and dissipative granular system.

Here we discuss the relation between our model and previous models of the liquid-glass transition, focusing on the difference in the basic standpoint among the models. We argue that (i) actual liquids universally have a tendency of spontaneous formation of locally favored structures and (ii) liquid-glass transition is controlled by the competition between long-range density ordering toward crystallization and short-range bond ordering toward the formation of locally favored structures due to the incompatibility in their symmetry. Thus, we regard vitrification as phenomena that are intrinsically related to crystallization. Previous models, on the other hand, regard vitrification as a result of (a) an homogeneous increase in the density and the resulting cooperativity in molecular motion or (b) the frustration intrinsic to a liquid state itself. Accordingly, they presuppose the kinetic avoidance of crystallization and thus do not put focus on `crystallization'. This leads to the essential difference in the physical picture between our model and previous models. By comparing models, we aim at gaining further insight into what is the physical origin of the liquid-glass transition and its possible connection with crystallization.
