Description
Commonly, normal diffusive behavior is characterized by a
linear dependence of the second central moment on time,
<x2(t)> ∝ t, while anomalous behavior
is expected to show a different time dependence,
<x2(t)> ∝ tδ; with
δ<1 for subdiffusive and δ>1 for
superdiffusive motions. I will demonstrate that this kind of
qualification, if applied straightforwardly, may be
misleading: There are anomalous transport motions revealing
perfectly "normal" diffusive character
<x2(t)> ∝ t, yet being non-Markov and
non-Gaussian in nature. Consequences of this paradoxical
diffusion for biophysical research will be briefly discussed.
