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…
