On polydispersity and the hard sphere glass transition.
We investigate the dynamics of polydisperse hard spheres at high packing fractions ϕ. We use extensive numerical simulations based on an experimentally-realistic particle size distribution (PSD) and compare to commonly-used PSDs such as Gaussian or top hat distribution. We find that the mode of kinetic arrest depends on the PSD's shape and not only on its variance. For the experimentally-realis...
متن کاملPhase coexistence in the hard-sphere Yukawa chain fluid with chain length polydispersity: dimer thermodynamic perturbation theory.
An extension of the dimer version of Wertheim's thermodynamic perturbation theory is proposed and used to treat polydisperse mixture of the hard-sphere Yukawa chain fluid with chain length polydispersity. The structure and thermodynamic properties of the reference system, represented by multicomponent mixture of the Yukawa hard-sphere dimers, are described using polymer mean spherical approxima...
متن کاملGaussian statistics of the hard-sphere fluid
By computer simulation of the hard-sphere fluid, we have determined the probabilities of observing N molecular centers within molecular sized volumes of the fluid. These probability distributions are found to be almost exactly Gaussian at medium densities. A maximum entropy prediction constructed from knowledge of the first two moments of the distribution and a prior distribution consistent wit...
متن کاملTension and stiffness of the hard sphere crystal-fluid interface.
A combination of fundamental measure density functional theory and Monte Carlo computer simulation is used to determine the orientation-resolved interfacial tension and stiffness for the equilibrium hard-sphere crystal-fluid interface. Microscopic density functional theory is in quantitative agreement with simulations and predicts a tension of 0.66k(B)T/σ(2) with a small anisotropy of about 0.0...
متن کاملKinetic model for the hard-sphere fluid and solid
The revised Enskog kinetic theory ~RET! for a system of hard spheres provides an exceptionally broad description of mesoscopic and macroscopic dynamics, applicable for both fluid and solid phases, long and short wavelengths, low and high densities, and exact at short times. This great potential is compromised by the difficulty of obtaining solutions outside the domain of linear response. In the...
