Simple MSA solution and thermodynamic theory in a hard-sphere Yukawa system

Integral-equation theory of polydisperse Yukawa systems

“…The "measured" static structure factor S (k) is introduced in the context of static light-scattering experiments [13,14] and is defined by (6) in which, for the form amplitudes b (k), we take the expression obtained for spheres with a homogeneous distribution of scattering material j&(kcr/2) b (k)~c r (7) Here j, is the spherical Bessel function of first order.…”

“…The main reason is due to the fact that an accurate and quantitative description of Yukawa systems is possible through closure relations, i.e. , [7,8]. Although to solve MSA equations is in principle simpler than to solve HNC or RY equations, difficulties in selecting acceptable solutions from the manifold of solutions prevented the application of MSA to cases with continuous polydispersity.…”

Yukawa fluid at a hard wall: field theory description

“…The results obtained in this paper, similar to [19], are presented for point particles with Yukawa interactions. We hope in the future to modify them for non point particles with Yukawa interactions using the mean spherical approximation result for homogeneous fluids [1,22] in a similar way as it was done for non point ionic systems [23].…”

Structure of multi-component/multi-Yukawa mixtures

“…In this work we will use the more common notation of BVH92. The case of factored interactions was discussed by Blum, [27,28] and by Ginoza [29,30,31,32]. The general solution of this problem [26] is given in terms of the scaling matrix Γ which will comply with the physical constraints of the systems (Blum et al [14,33,34]).…”
