Phase diagrams of Lennard‐Jones fluids

Phase diagrams of Lennard-Jones fluids

Smit and Frenkel’ have shown that the phase diagram of the two-dimensional Lennard-Jones fluid depends largely on the details of the truncation of the potential. In this Note, Gibbs-ensemble calculations are reported for the three-dimensional Lennard-Jones fluid. As expected, the phase diagram for this system also depends significantly on the details of the truncation. The Lennard-Jones potenti...

Global phase diagrams for dipolar fluids.

Fluids of molecules or particles interacting through dipole forces describe polar liquids and colloidal suspensions such as ferroQuids and electrorheological fluids. Phase diagrams for systems with strong dipolar coupling are not precisely known. Possible liquid state phase transitions include phase separation and spontaneous polarization. We present a set of generic phase diagrams for the Huid...

Phase diagrams of Janus fluids with up-down constrained orientations.

A class of binary mixtures of Janus fluids formed by colloidal spheres with the hydrophobic hemispheres constrained to point either up or down are studied by means of Gibbs ensemble Monte Carlo simulations and simple analytical approximations. These fluids can be experimentally realized by the application of an external static electrical field. The gas-liquid and demixing phase transitions in f...

Geochemical Phase Diagrams and Gale Diagrams

The problem of predicting the possible topologies of a geochemical phase diagram, based on the chemical formula of the phases involved, is shown to be intimately connected with and aided by well-studied notions in discrete geometry: Gale diagrams, triangulations, secondary fans, and oriented matroids.
