Freezing transition of hard hyperspheres.
We investigate the system of D-dimensional hard spheres in D-dimensional space, where D>3. For the fluid phase of these hyperspheres, we generalize scaled-particle theory to arbitrary D and furthermore use the virial expansion and the Percus-Yevick integral equation. For the crystalline phase, we adopt cell theory based on elementary geometrical assumptions about close-packed lattices. Regardle...
متن کاملSimulations of binary hard-sphere crystal-melt interfaces: interface between a one-component fcc crystal and a binary fluid mixture
The crystal-melt interfaces of a binary hard-sphere fluid mixture in coexistence with a single-component hard-sphere crystal is investigated using molecular-dynamics simulation. In the system under study, the fluid phase consists of a two-component mixture of hard spheres of differing size, with a size ratio α = 0.414. At low pressures this fluid coexists with a pure fcc crystal of the larger p...
متن کاملFreezing of binary mixtures of colloidal hard spheres
The freezing phase transition in a binary suspension of conoidal hard spheres of diameter ratio a = 0.61 was studied by light scattering and scanning electron microscopy. The suspensions consisted of stericaHy stabilized poly( methyl methacrylate) spheres of diameters about 670 and 407 nm suspended in a near refractive indexed matched suspension medium composed of carbon disulphide and cis-deca...
متن کاملMeasuring the equation of state of a hard-disc fluid
– We use video microscopy to study a two-dimensional (2D) model fluid of charged colloidal particles suspended in water and compute the pressure from the measured particle configurations. Direct experimental control over the particle density by means of optical tweezers allows the precise measurement of pressure as a function of density. We compare our data with theoretical predictions for the ...
متن کاملStability of orientationally disordered crystal structures of colloidal hard dumbbells.
We study the stability of orientationally disordered crystal phases in a suspension of colloidal hard dumbbells using Monte Carlo simulations. For dumbbell bond length L/sigma<0.4 with L the separation of the two spheres of the dumbbell and sigma the diameter of the spheres, we determine the difference in Helmholtz free energy of a plastic crystal with a hexagonal-close-packed (hcp) and a face-...
