We show that when Brownian motion takes place in a heterogeneous medium, the presence of local forces and transport coefficients leads to deviations from a Gaussian probability dis…

Entropically-induced asymmetric passage times of charged tracers across corrugated channels
Paolo Malgaretti, Ignacio Pagonabarraga, Miguel J Rubi
We analyze the diffusion of charged and neutral tracers suspended in an electrolyte embedded in a channel of varying cross-section. Making use of systematic approximations, the dif…
