Erratum: “Phase behavior of binary hard-sphere mixtures: Free volume theory including reservoir hard-core interactions” [J. Chem. Phys. 154, 074902 (2021)]

Abstract

In this erratum we identify two corrections to our paper.

Excluded volume interactions and phase stability in mixtures of hard spheres and hard rods

“…For binary HS mixtures, it has been shown that FF coexistence is metastable for all size ratios. 15 The results in Fig. 3 reveal that FF is predicted to become stable for sufficiently large g. Therefore, it is expected that a certain asphericity is required to stabilize a FF demixing region.…”

“…In contrast to original FVT predictions, the new FVT method predicts a critical aspect ratio g* below which fluid-fluid (FF) coexistence is metastable with respect to fluid-solid coexistence. This critical aspect ratio is expected because it has been shown that FF coexistence is metastable in binary hard-sphere mixtures for all size ratios 15 and HSC particles reduce to spheres in the limit of g -1. Moreover, FVT predicts that for a certain aspect ratio, there is not only a lower critical size ratio x* E 0.6 below which FF coexistence becomes metastable, but also an upper critical size ratio x* above which FF coexistence is metastable.…”

“…Here, we outline the FVT employed in this paper, which is based on previous work on binary HS mixtures 15 but extended to take the anisotropic shape of rod-like depletants into account. 27 In FVT the two compartments used are in osmotic equilibrium and the thermodynamic properties of the system can be described by the semi-grand potential O.…”

“…Opdam et al 15 improved the FVT approach by explicitly incorporating excluded volume interactions between the small HS depletants at all levels. The resulting FVT predictions were much closer to the computer simulations of Dijkstra et al 14 and also predicted the solid-solid phase equilibria.…”
