      abstract     = {The initial stage of isotropic-nematic spinodal demixing
                      kinetics of suspensions of very long and thin, stiff,
                      repulsive rods is analyzed on the basis of the N-particle
                      Smoluchowski equation. Equations of motion for the reduced
                      probability density function of the position and orientation
                      of a rod are expanded up to second order in spatial
                      gradients and leading order in orientational order
                      parameter. The resulting equation of motion is solved
                      analytically, from which the temporal evolution of
                      light-scattering patterns are calculated. It is shown that
                      inhomogeneities in number density are enslaved by the
                      temporal development of inhomogeneities in orientational
                      order. Furthermore, demixing due to rotational diffusion is
                      shown to be much faster as compared to translational
                      diffusion. This results in an instable mode that is
                      rotational, for which the corresponding eigenvector remains
                      finite at zero wave vector. The scattered intensity
                      nevertheless exhibits a maximum at a finite wave vector due
                      to the wave-vector dependence of time-exponential
                      prefactors. The wave vector where the intensity exhibits a
                      maximum is therefore predicted to be a function of time even
                      during the initial stage of demixing.},
