Number of branches in diffusion-limited aggregates: The skeleton
Stefan Schwarzer, Shlomo Havlin, Peter Ossadnik +1
We develop the skeleton algorithm to define the number of main branches of diffusion-limited aggregation (DLA) clusters. The skeleton algorithm provides a systematic way to r…
Non universal DLA and exact fractal dimensions
P. Ossadnik, C. -H. Lam, L. M. Sander
In analogy to recent results on non-universal roughening in surface growth [Lam and Sander, Phys. Rev. Lett. {\bf 69}, 3338 (1992)], we propose a variant of diffusion-limited aggre…
New model for crack growth using random walkers
Peter Ossadnik
In close analogy to diffusion limited aggregation (DLA) and inspired by a work of Roux, a random walker algorithm is constructed to solve the problem of crack growth in an elastic…
Power law tail in the radial growth probability distribution for DLA
Peter Ossadnik, Jysoo Lee
Using both analytic and numerical methods, we study the radial growth probability distribution for large scale off lattice diffusion limited aggregation (DLA) clusters. If…
Multiscaling analysis and width of the active zone of large off-lattice DLA
Peter Ossadnik
We measure the multiscaling behavior of large off-lattice diffusion limited aggregates (DLA). In contrast to previous studies we now find a continuous dependence of the multiscalin…
Cellular automaton for the fracture of disordered media
Peter Ossadnik
We study numerically the growth of a crack in an elastic medium under the influence of a travelling shockwave. We describe the implementation of a fast algorithm which is perfectly…
