Molecular Theory for the Freezing of the Classical One-Component Plasma

The "density functional" theory of freezing predicts that in the one-component plasma, (i) the density change on freezing is exactly zero, (ii) the liquid freezes to a bcc solid with an entropy change $\Delta S\approx -0.9\mathrm{Nk}$, and (iii) there exists a metastable fcc solid phase which has everywhere a slightly greater free energy than the bcc phase.
