Integral equation theory for dipolar hard sphere fluids with fluctuating orientational order

摘要: We present an integral equation approach to the structural and thermodynamic properties of a fluid partially aligned dipolar hard spheres. To relate two-particle correlation functions anisotropic singlet density, we mainly employ Lovett–Mou–Buff–Wertheim equation. show that, as in isotropic case, mean-spherical approximation reference hypernetted chain (RHNC) closures lead quite different results. This is particularly true at high coupling strengths, where RHNC theory shows transition from ferroelectric phase. The predicted temperatures are very close those one obtains for fluid.
