Batchelor, M. T.Henry, B. I.Roberts, A. P.2026-01-062026-01-061063-651XORCID:/0000-0001-6742-0518/work/162950049https://hdl.handle.net/1885/733803842We investigate the scaling of cluster size with mass for our simulations of diffusion-limited aggregation (DLA) clusters and dielectric-breakdown (DB) clusters of 106 particles grown on a square lattice, and DLA clusters of 106 particles grown off lattice. We find that the mass distribution and scaling behavior for the on-lattice DB model are intermediate between those for the on-lattice DLA model and the off-lattice DLA model. We take this as evidence that signatures of lattice anisotropy and the microscopic kinetics of attachment are both manifest at large length scales.4en199510.1103/PhysRevE.51.8070012434353
