Jamming and percolation of k3 -mers on simple cubic lattices
Jamming and percolation of three-dimensional (3D) k×k×k cubic objects (k3-mers) deposited on simple cubic lattices have been studied by numerical simulations complemented with finite-size scaling theory.

| Resumo: | Jamming and percolation of three-dimensional (3D) k×k×k cubic objects (k3-mers) deposited on simple cubic lattices have been studied by numerical simulations complemented with finite-size scaling theory. The k3-mers were irreversibly deposited into the lattice. Jamming coverage θj,k was determined for a wide range of k (2≤k≤40). θj,k exhibits a decreasing behavior with increasing k, being θj,k=∞=0.4204(9) the limit value for large k3-mer sizes. In addition, a finite-size scaling analysis of the jamming transition was carried out, and the corresponding spatial correlation length critical exponent νj was measured, being νj≈3/2. However, the obtained results for the percolation threshold θp,k showed that θp,k is an increasing function of k in the range 2≤k≤16. For k≥17, all jammed configurations are nonpercolating states, and consequently, the percolation phase transition disappears. The interplay between the percolation and the jamming effects is responsible for the existence of a maximum value of k (in this case, k=16) from which the percolation phase transition no longer occurs. Finally, a complete analysis of critical exponents and universality has been done, showing that the percolation phase transition involved in the system has the same universality class as the 3D random percolation, regardless of the size k considered. |
