Pseudopotential; phonon dispersion curves.

The phonon dispersion curves of some liquid metals, viz. Na $(Z = 1)$, Mg $(Z = 2)$, Al $(Z = 3)$ and Pb $(Z = 4)$, have been computed using our model potential. The charged hard sphere (CHS) reference system is applied to describe the structural information. Our model potential along with CHS reference system is capable of explaining the phonon dispersion relation for monovalent, divalent, trivalent and tetravalent liquid metals.
