Brownian yet non-Gaussian diffusion in heterogeneous media
內容簡介:A growing number of biological, soft, and active matter systems are
observed to exhibit anormal diffusive dynamics with a linear growth of the mean
square displacement, yet with a non-Gaussian distribution of increments. Based on theChubinsky-Slater idea of diffusing diffusivitiy, we here established and analyze aminimal model framework of diffusion processes with fluctuating diffusivity. Inparticular, we demonstrate the equivalence of diffusing diffusivity processes with asuperstatistical approach with a distribution of diffusivities, at times shorther than thediffusivity correlation time. At longer times, a crossover to a Gaussian distributionwith an effective diffusivity emerges. Specifically, we established a subordinationpicture of Brownian yet not Gaussian diffusion processes, which can be used for awide class of diffusivity fluctuation statistics. Our results are shown to be in excellentagreement with simulations and numerical evaluations.
