Figure 6
Vesicle in shear flow. In the top layer of the figure (a) we represent the short time rotational motion of the vesicle under shear flow. Two lipid beads corresponding to the outer layer are highlighted (yellow and green spheres) to help visualising the membrane rotation. The yellow and green beads remain aligned at a short time, but at a longer time, as we show in SI Fig. S4, the different lipid mobility in the bilayer causes their misalignment. In panels (b) and (c) we represent the time evolution of the normalised projection on the Z-axis of the system of two characteristic vectors of the vesicle: the eigenvector \({\Lambda }^{(3)}\) of the gyration tensor and associated to the longest axis of the prolate (b), and the vector \({\bf{v}}\) connecting one polar bead of the lipids in the membrane (yellow sphere) to the centre of mass of the vesicle (c). For the projection of the eigenvector we considered the absolute value.
