Density-Functional Theory of QuantumFreezing: Sensitivity to Liquid-State Structure and Statistics


Density-functional theory is applied to compute the groundstate energies of quantum hard-sphere solids. The modified weighteddensity approximation is used to map both the Bose and the Fermi solid onto a corresponding uniform Bose liquid, assuming negligible exchange for the Fermi solid. The required liquid-state input data are obtained from a paired phonon… (More)
