Anomalous diffusion, aging, and nonergodicity of scaled Brownian motion with fractional Gaussian noise: Overview of related experimental observations and models

W Wang, R Metzler, AG Cherstvy - Physical Chemistry Chemical …, 2022 - pubs.rsc.org
How does a systematic time-dependence of the diffusion coefficient D (t) affect the ergodic
and statistical characteristics of fractional Brownian motion (FBM)? Here, we answer this …

Understanding planet formation using microgravity experiments

G Wurm, J Teiser - Nature Reviews Physics, 2021 - nature.com
In 2018, images were released of a planet being formed around the star PDS 70, offering a
tantalizing glimpse into how planets come into being. However, many questions remain …

Emergent memory from tap** collisions in active granular matter

L Caprini, A Ldov, RK Gupta, H Ellenberg… - Communications …, 2024 - nature.com
In an equilibrium thermal environment, random elastic collisions between background
particles and a tracer establish the picture of Brownian motion fulfilling the celebrated …

[LIVRE][B] Wet granular matter: a truly complex fluid

S Herminghaus - 2013 - World Scientific
From our childhood, we remember the pasty consistency of wet sand, out of which we baked
our first 'cakes' in the sand box; soft enough to be squished and formed by our little hands …

Diffusion in multicomponent granular mixtures

AS Bodrova - Physical Review E, 2024 - APS
We investigate diffusion in polydisperse granular media. We derive the mean-squared
displacement of granular particles in a polydisperse granular gas in a homogeneous cooling …

Configuration-dependent dynamics of non-spherical particles in a gas–solid fluidized bed

C Zhang, R Zhu, Y Chen, W Wang… - Chemical Engineering …, 2023 - Elsevier
Configuration-dependent dynamics of non-spherical particles are investigated
experimentally in a quasi-two-dimensional gas–solid fluidized bed. We show that the vertical …

Diffusion of intruders in granular suspensions: Enskog theory and random walk interpretation

R Gómez González, E Abad, S Bravo Yuste, V Garzó - Physical Review E, 2023 - APS
The Enskog kinetic theory is applied to compute the mean square displacement of impurities
or intruders (modeled as smooth inelastic hard spheres) immersed in a granular gas of …

Kinetic theory of polydisperse granular mixtures: Influence of the partial temperatures on transport properties—A review

M García Chamorro, R Gómez González, V Garzó - Entropy, 2022 - mdpi.com
It is well-recognized that granular media under rapid flow conditions can be modeled as a
gas of hard spheres with inelastic collisions. At moderate densities, a fundamental basis for …

High-energy velocity tails in uniformly heated granular materials

Y Chen, J Zhang - Physical Review E, 2022 - APS
We experimentally investigate the velocity distributions of quasi-two-dimensional granular
materials uniformly heated by an electromagnetic vibrator, where the translational velocity …
