FIG. 5.

Density dependence of various excess entropies for the dumbbell at . Symbols represent different versions of the excess entropy as denoted within the legend.

Image of FIG. 6.
FIG. 6.

Translational, orientational, and total two-body excess entropies relative to the thermodynamic excess entropy for the dumbbell. Symbols represent different densities as denoted within the legend.

FIG. 8.

Relationship between reduced translational diffusivity and excess entropy for the dumbbell. The top, middle, and bottom panels provide this relationship with the translational two-body, total two-body, and thermodynamic excess entropies, respectively. Symbol shape and fill are consistent with the definition adopted in Fig. 6.

FIG. 9.

Relationship between reduced translational diffusivity and excess entropy for the dumbbell. The top, middle, and bottom panels provide this relationship with the translational two-body, total two-body, and thermodynamic excess entropies, respectively. Symbol shape and fill are consistent with the definition adopted in Fig. 7.

FIG. 10.

Relationship between reduced rotational diffusivity and excess entropy for the dumbbell. The top, middle, and bottom panels provide this relationship with the orientational two-body, total two-body, and thermodynamic excess entropies, respectively. Symbol shape and fill are consistent with the definition adopted in Fig. 6.

FIG. 11.

Relationship between reduced rotational diffusivity and excess entropy for the dumbbell. The top, middle, and bottom panels provide this relationship with the orientational two-body, total two-body, and thermodynamic excess entropies, respectively. Symbol shape and fill is consistent with the definition adopted in Fig. 7.

FIG. 12.

Relationship between reduced inverse relaxation time and thermodynamic excess entropy for the dumbbell. The upper curve provides the collective relaxation time and the lower curve corresponds to the rotational relaxation time. The collective relaxation time has been reduced by a factor of 10 such that both curves fit conveniently on a single plot. Symbol shape and fill are consistent with the definition adopted in Fig. 6.

FIG. 13.

Relationship between reduced translational diffusivity and the inverse-power-potential-based scaling variable . Symbol shape and fill are consistent with the definitions adopted in Figs. 6 and 7. Note the horizontal and vertical translation of the dumbbell data.

Image of FIG. 14.
FIG. 14.

Relationship between excess entropy and the inverse-power-potential-based scaling variable . Symbol shape and fill are consistent with the definitions adopted in Figs. 6 and 7.
