Preface: Characterisation of Physical Processes from Anomalous Diffusion Data

Anomalous diffusion, as it has come to be called, extends the concept of Brownian motion and is connected to disordered systems, non-equilibrium phenomena, flows of energy and information, and transport in living systems[3]. Anomalous diffusion is "non-universal" in the sense that physically very different systems share the same power-law form of the mean squared displacement x
