Abstract:
Percolation and jamming phenomena are investigated for random sequential deposition of rectangular needles on d=2 square lattices. Associated thresholds Pc perc and Pc jam are determined for various needle sizes. Their ratios Pc perc /Pc jam are found to be a constant \(0.62 \pm 0.01\) for all sizes. In addition the ratio of jamming thresholds for respectively square blocks and needles is also found to be a constant \(0.79 \pm 0.01\). These constants exhibit some universal connexion in the geometry of jamming and percolation for both anisotropic shapes (needles versus square lattices) and isotropic shapes (square blocks on square lattices). A universal empirical law is proposed for all three thresholds as a function of a.
