We investigated the Anderson transition in fractal-based complexes, which were generated using the dielectric-breakdown model when parameter α in the model was changed from α1 to α2 at time τ1 during the growth. When α1<α2, our nerve-cell-like complex can be considered a dendritic fractal grown on a somatic fractal. On the other hand, when α1>α2, our nebula-like complex cannot be divided into two regions. The...</α2,>

Anderson transition in a fractal-shaped structure is driven by running fractal dimension from two to three. We analyzed the spectral statistics of a quantum particle confined in a fractal-shaped structure generated using the dielectric breakdown model in three dimensions. When the fractal...
