Superstatistics and non-Gaussian diffusion

R Metzler - The European Physical Journal Special Topics, 2020 - Springer
Brownian motion and viscoelastic anomalous diffusion in homogeneous environments are
intrinsically Gaussian processes. In a growing number of systems, however, non-Gaussian …

Diffusing diffusivity: a model for anomalous, yet Brownian, diffusion

MV Chubynsky, GW Slater - Physical review letters, 2014 - APS
Wang et al.[Proc. Natl. Acad. Sci. USA 106, 15160 (2009)] have found that in several
systems the linear time dependence of the mean-square displacement (MSD) of diffusing …

Fickian non-Gaussian diffusion in glass-forming liquids

F Rusciano, R Pastore, F Greco - Physical Review Letters, 2022 - APS
Fickian yet non-Gaussian diffusion (FnGD), a most intriguing open issue in soft matter, is
generically associated with some dynamical and/or structural heterogeneity of the …

Rapid Fickian yet non-Gaussian diffusion after subdiffusion

R Pastore, A Ciarlo, G Pesce, F Greco, A Sasso - Physical Review Letters, 2021 - APS
The recently discovered Fickian yet non-Gaussian diffusion (FnGD) is here finely tuned and
investigated over a wide range of probabilities and timescales using a quasi-2D suspension …

Even hard-sphere colloidal suspensions display Fickian yet non-Gaussian diffusion

J Guan, B Wang, S Granick - ACS nano, 2014 - ACS Publications
We scrutinize three decades of probability density displacement distribution in a simple
colloidal suspension with hard-sphere interactions. In this index-matched and density …

Exceptionally slow movement of gold nanoparticles at a solid/liquid interface investigated by scanning transmission electron microscopy

A Verch, M Pfaff, N de Jonge - Langmuir, 2015 - ACS Publications
Gold nanoparticles were observed to move at a liquid/solid interface 3 orders of magnitude
slower than expected for the movement in a bulk liquid by Brownian motion. The nanoscale …

Unexpected crossovers in correlated random-diffusivity processes

W Wang, F Seno, IM Sokolov, AV Chechkin… - New Journal of …, 2020 - iopscience.iop.org
The passive and active motion of micron-sized tracer particles in crowded liquids and inside
living biological cells is ubiquitously characterised by'viscoelastic'anomalous diffusion, in …

Non-Gaussian displacement distributions in models of heterogeneous active particle dynamics

E Lemaitre, IM Sokolov, R Metzler… - New Journal of …, 2023 - iopscience.iop.org
We study the effect of randomly distributed diffusivities and speeds in two models for active
particle dynamics with active and passive fluctuations. We demonstrate how non-Gaussian …

Digital Fourier microscopy for soft matter dynamics

F Giavazzi, R Cerbino - Journal of Optics, 2014 - iopscience.iop.org
Soft matter is studied with a large portfolio of methods. Light scattering and video microscopy
