Disorder-induced Fickian, yet non-Gaussian diffusion in heterogeneous media

Fickian yet non-Gaussian diffusion is observed in several biological and soft matter systems, yet the underlying mechanisms behind the emergence of non-Gaussianity while retaining a linear mean-square displacement remain speculative. Here, we characterize quantitatively the effect of spatial heterog...
