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

[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
Configuration-dependent dynamics of non-spherical particles are investigated
experimentally in a quasi-two-dimensional gas–solid fluidized bed. We show that the vertical …

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