abstract = {<p style="text-align: justify;">We investigate the sedimentation dynamics of a binary mixture, the species
of which differ by their Stokes coefficients but are identical otherwise. We analyze
the sedimentation dynamics and the morphology of the final deposits using Brownian
dynamics simulations for mixtures with a range of sedimentation velocities of both
species. In addition, we use the lattice Boltzmann method to study hydrodynamic
effects. We found a threshold in the difference of the sedimentation velocities above
which the species in the final deposit are segregated. The degree of segregation increases with the difference in the Stokes coefficients or the sedimentation velocities
above the threshold. We propose a simple analytical model that captures the main
features of the simulated deposits.</p>},
