The fluid-solid transition of Dzugutov's potential

Abstract:

We have studied fluid-solid phase transformations of materials interacting via the Dzugutov potential V_Dz(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 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).
