Numerous examples for a priori unexpected non-Gaussian behaviour for normal and
anomalous diffusion have recently been reported in single-particle tracking experiments …

Vitrimers are functional cross-linked materials, exhibiting reprocessability, recyclability, and
healability, and thus these are expected for application as sustainable materials. The …

Brownian motion is a Gaussian process described by the central limit theorem. However,
exponential decays of the positional probability density function P (X, t) of packets of …

A generalized Langevin equation with fluctuating diffusivity (GLEFD) is proposed, and it is
shown that the GLEFD satisfies a generalized fluctuation-dissipation relation. If the memory …

We investigate Brownian motion with diffusivity alternately fluctuating between fast and slow
states. We assume that sojourn-time distributions of these two states are given by …

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 …

Diffusivity in some soft matter and biological systems changes with time, called the
fluctuating diffusivity. In this work, we propose a novel origin for fluctuating diffusivity based …

This study proposes applying the concept of fluctuating diffusivity (FD) to the diffusion of gas
molecules in cementitious materials, mainly through a two-state fluctuating diffusivity (2SFD) …

Superstatistical approaches have played a crucial role in the investigations of mixtures of
Gaussian processes. Such approaches look to describe non-Gaussian diffusion emergence …

Gaussian processes are powerful tools for modeling and predicting various numerical data.
Hence, checking their quality of fit becomes a vital issue. In this article, we introduce a …
