Non-Gaussianity in stochastic transport: phenomenology and modelling
Published 3 Apr 2022 in cond-mat.stat-mech | (2204.01048v1)
Abstract: Non-Gaussian shapes, despite a linear form of the mean-squared displacement, have been observed for the displacement distribution in a large range of diffusive systems. Stochastic models for such "Brownian yet non-Gaussian" diffusion will be introduced and discussed. Systems with non-Gaussian, anomalous diffusion will also be addressed.
