Controversial issues related to dye adsorption on clay minerals: a critical review

J Bujdák - Molecules, 2023 - mdpi.com
This critical review points out the most serious and problematic issues to be found in the
literature on the adsorption of dyes on clay minerals. The introduction draws attention to the …

Time averaging and emerging nonergodicity upon resetting of fractional Brownian motion and heterogeneous diffusion processes

W Wang, AG Cherstvy, H Kantz, R Metzler, IM Sokolov - Physical Review E, 2021 - APS
How different are the results of constant-rate resetting of anomalous-diffusion processes in
terms of their ensemble-averaged versus time-averaged mean-squared displacements …

Active Brownian motion with directional reversals

I Santra, U Basu, S Sabhapandit - Physical Review E, 2021 - APS
Active Brownian motion with intermittent direction reversals is common in bacteria like
Myxococcus xanthus and Pseudomonas putida. We show that, for such a motion in two …

Cusp of non-Gaussian density of particles for a diffusing diffusivity model

M Hidalgo-Soria, E Barkai, S Burov - Entropy, 2021 - mdpi.com
We study a two state “jumping diffusivity” model for a Brownian process alternating between
two different diffusion constants, D+> D−, with random waiting times in both states whose …

Target Search Problems

D Grebenkov, R Metzler, G Oshanin - Target Search Problems, 2024 - Springer
This chapter presents an introduction to the Target Problem. It contains a brief description of
the origins of its name, an exposition of a historical background and an overview of different …

Temperature and friction fluctuations inside a harmonic potential

Y Lanoiselée, A Stanislavsky, D Calebiro, A Weron - Physical Review E, 2022 - APS
In this article we study the trapped motion of a molecule undergoing diffusivity fluctuations
inside a harmonic potential. For the same diffusing-diffusivity process, we investigate two …

Anomalous diffusion: fractional Brownian motion vs fractional Ito motion

I Eliazar, T Kachman - Journal of Physics A: Mathematical and …, 2022 - iopscience.iop.org
Generalizing Brownian motion (BM), fractional Brownian motion (FBM) is a paradigmatic
selfsimilar model for anomalous diffusion. Specifically, varying its Hurst exponent, FBM …

Regular and anomalous diffusion: I. Foundations

I Eliazar - Journal of Physics A: Mathematical and Theoretical, 2024 - iopscience.iop.org
Diffusion is a generic term for random motions whose positions become more and more
diffuse with time. Diffusion is of major importance in numerous areas of science and …

Exact calculation of the mean first-passage time of continuous-time random walks by nonhomogeneous Wiener–Hopf integral equations

M Dahlenburg, G Pagnini - Journal of Physics A: Mathematical …, 2022 - iopscience.iop.org
We study the mean first-passage time (MFPT) for asymmetric continuous-time random walks
in continuous-space characterised by waiting-times with finite mean and by jump-sizes with …
