Note: An exact scaling relation for truncatable free energies of polydisperse hard-sphere mixtures
arXiv:1202.0672 · doi:10.1063/1.3702439
Abstract
A theoretical model for polydisperse systems of hard spheres is said to be truncatable when the excess free energy depends on the size distribution through a finite number $K$ of moments. This Note proves an exact scaling relation for truncatable free energies, which allows to reduce the effective degrees of freedom to $K-2$ independent combinations of the moments.
