Metastable liquid-liquid coexistence and density anomalies in a core-softened fluid
Metastable liquid-liquid coexistence and density anomalies in a core-softened fluid
Linearly sloped or ``ramp'' potentials belong to a class of core-softened models which possess a liquid-liquid critical point (LLCP) in addition to the usual liquid-gas critical point. Furthermore, they exhibit thermodynamic anomalies in their density and compressibility, the nature of which may be akin to those occurring in water. Previous …
