Figure 6: (a) Number of particles which diffused a distance tex2html_wrap_inline823 in tex2html_wrap_inline825 msec from a sample of 15000 trajectory steps. The thin line is a fit to eqn. (16). (b) The evolution in time of the square of the width, tex2html_wrap_inline827 , from fits such as that in (a). The linear least-squares fit to eqn. (17) provides a measurement of the spheres' long-time self-diffusion coefficient. The unresolvable offset tex2html_wrap_inline829 in this fit is consistent with our estimated measurement error for particle locations for a dilute suspension with minimal caging.
