Surface Hardening and Self-Organized Fractality Through Etching of Random Solids
A. Gabrielli, A. Baldassarri, B. Sapoval
When a finite volume of etching solution is in contact with a disordered solid, complex dynamics of the solid-solution interface develop. If the etchant is consumed in the chemical…

A Hierarchical Model of Slow Constrained Dynamics
M. A. Muñoz, A. Gabrielli, H. Inaoka +1
We introduce a new simple hierarchically constrained model of slow relaxation. The configurational energy has a simple form as there is no coupling among the spins defining the sys…

Laplacian Fractal Growth in Media with Quenched Disorder
R. Cafiero, A. Gabrielli, M. Marsili +2
We analyze the combined effect of a Laplacian field and quenched disorder for the generation of fractal structures with a study, both numerical and theoretical, of the quenched die…
