N. Vandewalle et M. Ausloos, LACUNARITY, FRACTAL, AND MAGNETIC TRANSITION BEHAVIORS IN A GENERALIZED EDEN GROWTH-PROCESS, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 50(2), 1994, pp. 180000635-180000638
The effect of an internal extra degree of freedom introduced into the
simplest growth model (the Eden model) leads to a joint physical and g
eometrical transition. Lacunarity, fractal, and magnetic transitions a
re indeed reported to be at the same critical values of the growth par
ameters. A logarithmic behavior of the cluster mass on this critical v
alue was found.
