Abstract

We have studied fluid-solid phase transformations of materials interacting via the Dzugutov potential VDz(r) (Phys. Rev. A 46, R2984 (1992)). We present evidence from molecular dynamics simulations that this interaction does not exhibit a liquid phase. If a mixed potential Vmix(r) is formed by a linear superposition of VDz(r)and the Lennard-Jones potential VLJ(r), then the liquid phase disappears at a fraction of less than 60% VLJ(r).
