Abstract
Precise thresholds for site percolation on eight Archimedean lattices are determined by the hull-walk gradient-percolation simulation method, with the results honeycomb or 0.807 904 0.747 806 (4,6,12), 0.729 724 0.579 498 0.621 819 (3,4,6,4), 0.550 213 and 0.550 806 with errors of about [The remaining Archimedean lattices are the square triangular and Kagomé (3,6,3,6), for which is already known exactly or to a high degree of accuracy.] The numerical result for the lattice is consistent with the exact value The values of for all 11 Archimedean lattices, as well as a number of nonuniform lattices, are found to be well correlated by a nearly linear function of a generalized Scher-Zallen filling factor. This correlation is much more accurate than recently proposed correlations based solely upon coordination number.
