Microscopic structure and thermodynamics of a core-softened model fluid from the second-order integral equations theory

We have studied the structure and thermodynamic properties of isotropic three dimensional core-softened fluid by using the second-order Ornstein-Zernike integral equations completed by the hypernetted chain and Percus-Yevick closures. The radial distribution functions are compared with those from si...

Ми дослiдили структурнi i термодинамiчнi властивостi однорiдного тривимiрного плину з пом’якшеним кором, використовуючи iнтегральнi рiвняння Орнштейна - Цернiке другого порядку i згiперланцюговим замиканням та замиканням Перкуса - Євiка. Зроблено порiвняння радiальних функцiй розподiлу з вiдповiдними функцiями, отриманими iз синглетнихiнтегральних рiвнянь, а також з даними комп’ютерного моделювання. З рiзних наближених теорiй встановлено границi областi аномалiї густини. Отриманi результати показують, що гiперланцюгове наближення iнтегральних рiвнянь другого порядку може бути використане для опису як структури, так i аномалiї густини цього модельного плину.
