Isostructural solid–solid transitions in binary asymmetrical hard sphere system: Based on solvent-mediated potential

摘要: Abstract Size dependence is imparted onto a modified bridge functional, adopted for recently proposed semi-analytical hard sphere reference system theory calculation of solvent-mediated potential (SMP). The SMP two large particles immersed in small solvent bath predicted by the present improved version satisfactory agreement with prediction from theoretically based fitting formula. Isostructural solid–solid transitions binary asymmetrical are investigated on single-component macrofluid approximation combined version. It found that isostructural transition appears when size asymmetry increases. limiting ratio near 1 / 8 . As increases, critical density both and components fcc increases decreases, respectively.
