Contribution
It provides a detailed calculation of coupled diffusion coefficients in stacked membranes, highlighting the hydrodynamic interactions between membranes.
Findings
Hydrodynamic coupling affects particle diffusion in stacked membranes.
Both longitudinal and transverse diffusion coefficients are influenced by membrane interactions.
Stacked geometry induces significant hydrodynamic effects between membranes.
Abstract
The coupled in-plane diffusion dynamics between point-particles embedded in stacked fluid membranes are investigated. We calculate the contributions to the coupling longitudinal and transverse diffusion coefficients due to particle motion within the different as well as the same membranes. The stacked geometry leads to a hydrodynamic coupling between the two membranes.
