Vesicle motion.
(a) Mean square displacement of the vesicle center of mass for ϕ = 0.16 and Nb = 100. Data correspond to the cases of elongated swimmers (blue symbols) and spherical swimmers (green symbols). The red curve is the theoretical prediction given by Eq. (19). The red dashed curve is the theoretical mean square displacement of a free run-and-tumble particle. (b) Diffusion coefficient normalized to the reduced value Dv(Ns) for elongated (blue symbols) and spherical (green symbols) swimmers as a function of swimmer density ϕ (Nb = 100). The parameters are obtained by fitting the data with Eq. (19). The black dashed line is Dfit/Dv = 1.
