... Diffusion governed by Brownian motion is an efficient transport mechanism on short time and length scales. ... A Brownian particle will rapidly explore a heterogeneous environment that in turn strongly alters its trajectory. ... It is well known that the non-negligible fluid's inertia leads to hydrodynamic memory effects [1] resulting in a characteristic long-time tail of t -3/2 in the velocity correlations of the particle's motion. ... 2007 Biophysics dep., ...
