The fluid-solid transition of Dzugutov's potential

We have studied fluid-solid phase transformations of materials interacting via the Dzugutov potential V-Dz(r) (Phys. Rev. A 48, R2984 (1992)). We present evidence from molecular dynamics simulations that this interaction does not exhibit a liquid phase. If a mixed potential V-mix(r) is formed by a linear superposition of V-Dz(r) and the Lennard-Jones potential V-LJ(r), then the liquid phase disappears at a fraction of less than 60% V-LJ(r).
