By combining interface-pinning simulations with numerical integration of the Clausius-Clapeyron equation, we accurately determine the melting-line coexistence pressure and fluid/crystal densities of the Weeks-Chandler-Andersen system, covering four decades of temperature. The data are used for comparing the melting-line predictions of the Boltzmann, Andersen-Weeks-Chandler, Barker-Henderson, and Stillinger hard-sphere approximations. The Andersen-Weeks-Chandler and Barker-Henderson theories…

Phase diagram of the Weeks-Chandler-Andersen potential from very low to high temperatures and pressures.

A combination of two molecular simulation algorithms has been used to determine the solid-liquid coexistence of the Weeks-Chandler-Andersen (WCA) fluid from low temperatures up to very high

The melting line of the Weeks–Chandler–Anderson Lennard‐Jones reference system

The purpose of this paper is to study the role of repulsive and attractive forces on the melting behavior of simple substances. The melting line of the purely repulsive Weeks–Chandler–Anderson

Application of cell models to the melting and sublimation lines of the Lennard-Jones and related potential systems.

This work combining HCM and MD simulations provides a comparison of the melting and sublimation lines of the LJ system, which could provide the foundations for a more unified statistical mechanical description of these two solid boundary lines.

Two-step melting of the Weeks-Chandler-Anderson system in two dimensions.

A detailed numerical simulation study of a two-dimensional system of particles interacting via the Weeks-Chandler-Anderson potential, the repulsive part of the Lennard-Jones potential, shows aTwo-step melting: a continuous melting of solid to hexatic phase, followed by a first-order melting of hexatic to liquid.

On the choice of the effective diameter in the high-temperature expansion for the Lennard–Jones fluid

A third-order perturbation theory, within the framework of the high temperature expansion, with the perturbation terms obtained from computer simulation, is used to test the performance of several

Equilibrium fluid-solid coexistence of hard spheres.

We present a tethered Monte Carlo simulation of the crystallization of hard spheres. Our method boosts the traditional umbrella sampling to the point of making practical the study of constrained

Integral equation theory of thermodynamics, pair structure, and growing static length scale in metastable hard sphere and Weeks-Chandler-Andersen fluids.

We employ the Ornstein-Zernike integral equation theory with the Percus-Yevick (PY) and modified-Verlet (MV) closures to study the equilibrium structural and thermodynamic properties of metastable

Hard sphere perturbation theory for fluids with soft-repulsive-core potentials.

This work derives an analytic expression for Mon's correction in terms of the radial distribution function of the soft-core fluid, g(0)(r), approximated using Lado's self-consistent extension of Weeks-Chandler-Andersen (WCA) theory.

Thermodynamics of freezing and melting

A theory in which properties of the coexisting crystal and liquid phases at a single thermodynamic state point provide the basis for calculating the pressure, density and entropy of fusion as functions of temperature along the melting line, as well as the variation along this line of the reduced crystalline vibrational mean-square displacement (the Lindemann ratio), and the liquid's diffusion constant and viscosity.
