Enhanced diffusion on a one-dimensional fractal

Anomalous diffusion is known to occur in many fractal structures. The distance covered in time t is given by 〈r 2〉∼t 2 d w with d W ≠2 . Usually sub-diffusive behaviour with d W >2 is found in fractals. We report a computer simulation study of diffusion on a Cantor-bar like lattice, showing that...

Description
Summary:Anomalous diffusion is known to occur in many fractal structures. The distance covered in time t is given by 〈r 2〉∼t 2 d w with d W ≠2 . Usually sub-diffusive behaviour with d W >2 is found in fractals. We report a computer simulation study of diffusion on a Cantor-bar like lattice, showing that under certain circumstances, enhanced diffusion with d W
