Crystallization and phase separation in nonadditive binary hard-sphere mixtures

摘要

We calculate for the first time the full phase diagram of an asymmetric nonadditive hard-sphere mixture. The nonadditivity strongly affects the crystallization and the fluid-fluid phase separation. The global topology of the phase diagram is controlled by an effective size ratio y(eff), while the fluid-solid coexistence scales with the depth of the effective potential well. [References: 33]
