Almarza, N. G. ; Lomba, Enrique ; Ruiz, Guiomar ; Fernández Tejero, Carlos | American Physical Society | 2001-03-05Evidence of a liquid-liquid equilibrium in simple fluids has recently been exposed for a density-dependent pair potential in the framework of a van der Waals theory. Here this double criticality is investigated by means of computer simulation, a[...]texto impreso
The modified weighted density approximation is investigated in order to determine the thermodynamics of the ordered CsCl and NaCl structures. Our results indicate that one of the essential assumptions of the theory, namely, the uniform fluid lim[...]
