Rapid Fickian Yet Non-Gaussian Diffusion after Subdiffusion
Abstract
The recently discovered Fickian yet non-Gaussian diffusion (FnGD) is here finely tuned and investigated over a wide range of probabilities and timescales using a quasi-2D suspension of colloidal beads under the action of a static and spatially random optical force field. This experimental model allows one to demonstrate that a ``rapid'' FnGD regime with a diffusivity close to that of free suspension can originate from earlier subdiffusion. We...
