Phys. Rev. E 63, 061501 (2001) [5 pages]Liquid-liquid equilibrium for monodisperse spherical particlesReceived 23 June 2000; published 18 May 2001 A system of identical particles interacting through an isotropic potential that allows for two preferred interparticle distances is numerically studied. When the parameters of the interaction potential are adequately chosen, the system exhibits coexistence between two different liquid phases (in addition to the usual liquid-gas coexistence). It is shown that this coexistence can occur at equilibrium, namely, in the region in which the liquid is thermodynamically stable. © 2001 The American Physical Society URL:
