Rods in the smectic phase: 1-D Brownian diffusion in a periodic potential — •Pavlik Lettinga1 and Eric Grelet2 — 1Forschungszentrum Jülich, Jülich, Germany — 2CRPP-CNRS, Pessac, France
We report the direct visualization at the scale of single particles of mass transport between smectic layers, also called permeation, in a suspension of rodlike viruses. We show that this diffusion effectively can be described by 1-D diffusion of a Brownian particle in a periodic potential. We compare this diffusion with diffusion of rods in the isotropic and nematic phase.
