Metastable structures with modified weighted density-functional theory.
The free energy of the supercooled liquid near freezing is studied in the density-functional approach using the modified weighted density approximation. A class of minima corresponding to heterogeneous structures characterized by weak mass localization are detected. The stability of these structures is found to be greater than the highly localized "hard-sphere glass" state in the intermediate density range above freezing.
