Abstract
Anomalous diffusion is known to occur in many fractal structures. The distance covered in time t is given by r2! approximately t2/dw with d (w) not-equal 2. Usually sub-diffusive behaviour with d(w)>2 is found in fractals. We report a computer simulation study of diffusion on a C antor-bar like lattice, showing that under certain circumstances, enha nced diffusion with d(w)<2 may be observed.
