This paper proposes a simple model of anomalous diffusion, in which a particle moves with the velocity field induced by a single “dipole” (a doublet or a pair of source and sink), whose moment is modulated randomly at each time step. A motivation to introduce such a model is that it may serve as a toy model to investigate an anomalous diffusion of fluid particles in turbulence. We perform a numerical simulation of the fractal dimension of the trajectory using periodic boundary conditions in two and…

Analytical Study of Anomalous Diffusion by Randomly Modulated Dipole
This paper derives the Fokker-Planck (FP) equation for a particle moving in potential by a randomly modulated dipole. The FP equation describes the anomalous diffusion observed in the companion paper

Self-Similar Decay in the Kraichnan Model of a Passive Scalar
We study the two-point correlation function of a freely decaying scalar in Kraichnan's model of advection by a Gaussian random velocity field that is stationary and white noise in time, but
Anomalous Diffusion: A Basic Mechanism for the Evolution of Inhomogeneous Systems
In this article we review classical and recent results in anomalous diffusion and provide mechanisms useful for the study of the fundamentals of certain processes, mainly in condensed matter physics,
Taylor dispersion in two-dimensional bacterial turbulence.
In this work, single particle dispersion was analyzed for a bacterial turbulence by retrieving the virtual Lagrangian trajectory via numerical integration of the Lagrangian equation. High-order
Anomalous diffusion models and their properties: non-stationarity, non-ergodicity, and ageing at the centenary of single particle tracking.
TLDR
This Perspective is intended as a guidebook for both experimentalists and theorists working on systems, which exhibit anomalous diffusion, and pays special attention to the ergodicity breaking parameters for the different anomalous stochastic processes.
Taylor particle dispersion during transition to fully developed two-dimensional turbulence.
TLDR
New measurements of single particle dispersion in turbulent two-dimensional (2D) flows reveal a transition from weakly dispersing superdiffusive regime to strongly dispersing Brownian diffusion as the flow energy is increased in a broad range.
Diffusion with resetting in arbitrary spatial dimension
We consider diffusion in arbitrary spatial dimension d with the addition of a resetting process wherein the diffusive particle stochastically resets to a fixed position at a constant rate $r$. We
Fractal dimension of superfluid turbulence.
TLDR
A kinematic model of normal-fluid turbulence is developed to study superfluid vortex tangles at finite temperatures and it is found that the fractal dimension is directly related to the vortex-line density and is independent of temperature over a wide range.
