Depletion induced demixing in polydisperse mixtures of hard spheres
Richard P. Sear
Polydisperse mixtures are those in which components with a whole range of sizes are present. It is shown that the fluid phase of polydisperse hard spheres is thermodynamically unst…
The low temperature interface between the gas and solid phases of hard spheres with a short-ranged attraction
Richard P. Sear
At low temperature, spheres with a very short-ranged attraction exist as a close-packed solid coexisting with an infinitely dilute gas. We find that the ratio of the interfacial te…
Phase separation and crystallisation of polydisperse hard spheres
Richard P. Sear
Hard spheres with a polydispersity above approximately 8% are shown to crystallise into two phase-separated solid phases. A polydispersity above 8% is too large to be tolerated by…
The stability limit of polydisperse sticky hard spheres
Richard P. Sear
It has been shown by Stell [J. Stat. Phys. 63, 1203 (1991)] that at low temperature monodisperse sticky spheres collapse to form coexisting close-packed solid and infinitely dilute…
