Quasistationary (QS) simulations yield the critical particle density to high precision [$p_c = 0.7112687(2)$], and show that the diffusion constant scales in the same manner as the activity density, as found previously in the one-dimensional case. Short-time scaling is characterized by subdiffusive behavior (mean-square displacement $\\sim t^\\gamma$ with $\\gamma < 1$), which is easily understood as a consequence of the in","authors_text":"Gandhimohan M.
