Random diffusivity from stochastic equations: comparison of two models for Brownian yet non-Gaussian diffusion

A considerable number of systems have recently been reported in which Brownian yet non-Gaussian dynamics was observed. These are processes characterised by a linear growth in time of the mean squared displacement, yet the probability density function of the particle displacement is distinctly non-Ga...
