By using molecular dynamics simulations on a large number of hard spheres and the Voronoï tessellation we characterize hard-sphere systems geometrically at any packing fraction eta along the different branches of the phase diagram. Crystallization of disordered packings occurs only for a small range of packing fraction. For the other packing fractions the(More)
Three-dimensional (3D) disordered media may be studied by performing random planar cuts through the material and trying to go back to 3D geometry from two-dimensional information. We have studied from this point of view numerical packings of spheres of two sizes for which the radii of the spheres and the composition of the mixtures have been obtained from(More)
We study the effect of the anisotropy of the cells on the topological properties of monodisperse two- and three-dimensional (3D) froths. These froths are built by Voronoï tessellation of actual assemblies of monosize disks (2D) and of many numerical packings of monosize disks (2D) and spheres (3D). We show that some topological properties of these froths(More)
