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 [1] and breaks the conservation of the total probability at the singularity by the dipole. It also shows anisotropic diffusion, which is typical in fluid turbulence. We need to modify the probability density by introducing a mechanism to recover the particle. After the modification, the latent fractal…

Anomalous diffusion in a randomly modulated velocity field
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

Nonlinear anomalous diffusion equation and fractal dimension: exact generalized Gaussian solution.
In this work we incorporate, in a unified way, two anomalous behaviors, the power law and stretched exponential ones, by considering the radial dependence of the N-dimensional nonlinear diffusion

Stochastic geometry of critical curves, Schramm–Loewner evolutions and conformal field theory
Conformally invariant curves that appear at critical points in two-dimensional statistical mechanics systems and their fractal geometry have received a lot of attention in recent years. On the one
Scaling limits of loop-erased random walks and uniform spanning trees
AbstractThe uniform spanning tree (UST) and the loop-erased random walk (LERW) are strongly related probabilistic processes. We consider the limits of these models on a fine grid in the plane, as the
