Stable centred tetragonal phases in the hard core Yukawa system.
The hard core Yukawa system, consisting of particles with an impenetrable core and interacting via a repulsive Yukawa pair potential, is known to solidify either in a bcc or fcc crystal. Using optimization strategies based on genetic algorithms we give evidence that at zero temperature an additional centred tetragonal phase structure in the range of high packing fractions emerges.
متن کاملA Hard Convex Core Yukawa Equation of State for Nonassociated Chain Molecules
The compressibility factor of nonassociated chain molecules composed of hard convex core Yukawa segments was derived with SAFT-VR and an extension of the Barker-Henderson perturbation theory for convex bodies. The temperature-dependent chain and dispersion compressibility factors were derived using the Yukawa potential. The effects of temperature, packing fraction, and segment number on the com...
متن کاملirial coefficients of hard - core attractive Yukawa fluids
We used Mayer sampling technique—a method based on free energy perturbation, to calculate virial coefficients B2–B6 for hard-core Yukawa fluids with interaction range parameter, =1.8, 3.0, 4.0, 5.0, 8.0, 9.0, and 10. We used these coefficients in the virial equation of state (VEOS) to obtain compressibility vailable online 28 June 2009
متن کاملPhase diagrams of hard-core repulsive Yukawa particles.
We determine the phase behavior of hard spheres interacting with repulsive Yukawa (screened Coulomb) interaction using computer simulations. We study the effect of the hard-core diameter on the phase behavior of repulsive Yukawa particles by comparing our phase diagrams with that of repulsive point Yukawa particles. We show that for sufficiently high contact values of the pair potential (betaep...
متن کاملPhase diagram of a binary symmetric hard-core Yukawa mixture.
We assess the accuracy of the self-consistent Ornstein-Zernike approximation for a binary symmetric hard-core Yukawa mixture by comparison with Monte Carlo simulations of the phase diagrams obtained for different choices of the ratio alpha of the unlike-to-like interactions. In particular, from the results obtained at alpha=0.75 we find evidence for a critical endpoint in contrast to recent stu...
