Single-file diffusion in spatially inhomogeneous systems
Benjamin Sorkin, David S. Dean
We study the effect of spatially-varying potential and diffusivity on the dispersion of a tracer particle in single-file diffusion. Non-interacting particles in such a system exhib…
Interactions enhance dispersion in fluctuating channels via emergent flows
Yating Wang, David S. Dean, Sophie Marbach +1
Understanding particle motion in narrow channels is essential to guide progress in numerous applications, from filtration to vascular transport. Thermal or active fluctuations of c…
Effusion of stochastic processes on a line
David S. Dean, Satya N. Majumdar, Gregory Schehr
We consider the problem of leakage or effusion of an ensemble of independent stochastic processes from a region where they are initially randomly distributed. The case of Brownian…
Non-Gaussian diffusion near surfaces
Arthur Alexandre, Maxime Lavaud, Nicolas Fares +6
We study the diffusion of particles confined close to a single wall and in double-wall planar channel geometries where the local diffusivities depend on the distance to the boundar…
Nanoparticle Taylor dispersion near charged surfaces with an open boundary
Alexandre Vilquin, Vincent Bertin, Elie Raphaël +3
The dispersive spreading of microscopic particles in shear flows is influenced both by advection and thermal motion. At the nanoscale, interactions between such particles and their…
How stickiness can speed up diffusion in confined systems
Arthur Alexandre, Matthieu Mangeat, Thomas Guérin +1
The paradigmatic model for heterogeneous media used in diffusion studies is built from reflecting obstacles and surfaces. It is well known that the crowding effect produced by thes…
