Anomalous behaviors in fractional Fokker-Planck equation

K Kim, YS Kong - arXiv preprint cond-mat/0207047, 2002 - arxiv.org
We introduce a fractional Fokker-Planck equation with a temporal power-law dependence
on the drift force fields. For this case, the moments of the tracer from the force-force …
