Being heterogeneous is disadvantageous: Brownian non-Gaussian searches

V Sposini, S Nampoothiri, A Chechkin, E Orlandini… - Physical Review E, 2024 - APS
Diffusing diffusivity models, polymers in the grand canonical ensemble and polydisperse,
and continuous-time random walks all exhibit stages of non-Gaussian diffusion. Is non …

Simple fluctuations in simple glass formers

CCL Laudicina, P Charbonneau, Y Hu… - The Journal of …, 2024 - ACS Publications
Critical single-particle fluctuations associated with particle displacements are inherent to
simple glass-forming liquids in the limit of large dimensions and leave a pseudocritical trace …

On the interpretation of mean-square displacement in heterogeneous systems

MG Li, R Xing, LM Fan, M Hu, JD Bao… - New Journal of …, 2024 - iopscience.iop.org
When dealing with heterogeneous systems, interpreting the mean-square displacement
(MSD) data appropriately is crucial. This is due to the limitation that the various …

RK Singh, S Burov - arXiv preprint arXiv:2410.23112, 2024 - arxiv.org
In transport processes across materials like glasses, living cells, and porous media, the
probability density function of displacements exhibits exponential decay rather than …

Two-states Brownian particle in a Harmonic Potential

GB Carollo, G Gonnella, D Moretti, A Suma… - arXiv preprint arXiv …, 2024 - arxiv.org
We study the behaviour of a Brownian particle in the overdamped regime in the presence of
a harmonic potential, assuming its diffusion coefficient to randomly jump between two …
