Disorder-induced Fickian, yet non-Gaussian diffusion in heterogeneous media
Authors: Indrani Chakraborty, Yael Roichman

Type: Publication
Abstract: This paper shows how disorder in the arrangement of obstacles induces Fickian yet non-Gaussian diffusion of tracer particles. The authors show that superstatistical behavior, arising from spatial heterogeneity, leads to non-Gaussianity via two coupled physical mechanisms.
Popularity: This indicator reflects the "current" impact/attention (the "hype") of an article in the research community at large, based on the
underlying citation network.
Influence: This indicator reflects the overall/total impact of an article in the research community at large, based on the
underlying citation network (diachronically).
Citation Count: This is an alternative to the "Influence" indicator, which also reflects the overall/total impact of an article in
the research community at large, based on the underlying citation network (diachronically).
Impulse: This indicator reflects the initial momentum of an article directly after its publication, based on the underlying citation
network.
