The full steady-state distribution can be computed exactly in any space dimension d. Dynamical heterogeneities are characterized by a length scale that diverges when approaching the critical density. The glassy dynamics of the model can be described as a reaction-diffusion process for the mobile regions. The motion of mobile regions is found to be subdiffusive, for a large range of parameters, due to a self-induced trapping mechanism.4 pages, 4 figuresDisordered Systems and Neural NetworksStatistical MechanicsSubdiffusion and dynamical heterogeneities in a lattice glass modeltext
