Several recent experiments identify unusual patterns in particle diffusion, hinting at some underlying complexity in the process which physicists have yet to discover. Through new analysis published ...

The milky pattern on the surface of the foamed coffee provides a delicious example of… anomalous diffusion in an inhomogeneous medium. A drop of dye added to a glass of water undergoes ordinary ...

This diagram illustrates the distribution of charges on clay particles within a solution and the structure of the surrounding diffuse double layer. The diffuse double layer of clay minerals will form ...

I study the statistics of many particles diffusing in a common, space-time random environment which introduces correlations in the movement of nearby particles. My work has shown that outlying ...

Around a decade ago, the discovery of Fickian yet non-Gaussian Diffusion (FnGD) in soft and biological materials broke up the celebrated Einstein's picture of Brownian motion. To date, such an ...
