Abstract:
The structures of the models of the Lennard-Jones liquid and mercury, cesium, and rubidium melts have been investigated. According to the local order dominant in a system, three regions have been selected in the phase diagrams of the models. For the Lennard-Jones model, the transition between the selected regions corresponds to a change in the asymptotic behavior of the radial distribution function. For the Hg, Cs, and Rb models, the position of the boundaries between these regions correlates with the specific features of the physical properties of these materials. © Allerton Press, Inc. 2008.
