In the recent decades anomalous diffusion have attracted much attention thanks to its extreme importance in many physical fields, e.g.tracer transport through porous media, turbulence [1], nuclear proliferation, chemistry, biology, environmental sciences, even in economics and finance.The mean square displacement (MSD) of a diffusing particle can be stated as < x2 (t) >∝ t in the normal diffusion, but the MSD has been observed exhibiting < x 2 (t) >∝tα, in anomalous diffusion and can be a constant[2], larger or smaller than 1.
