Molecular Dynamics of the Sedimentation of polydisperse colloids

We have performed molecular dynamics simulation on colloidal systems composed of~polydispersed hard spheres. The polydispersivity in the~systems had a Gaussian distribution~with a range of up to 10{\%}. ~We studied system where gravity plays a fundamental role. We show the sedimentation profiles and the effects on layering and crystallization for different values of the gravitational length, polidispersivity and area density of the system.
