Phonon dispersion curves of equiatomic liquid alloys

In the present paper, the phonon dispersion curves (PDC) of some equiatomic liquid alkali binary alloys are reported in second order approach through the equation given by Hubbard and Beeby (HB). The pair correlation function g(r) is directly computed from the interatomic pair potential, which is used in the present computation. Two different forms of local field correction functions proposed by Hartree (H) and Ichimaru-Utsumi (IU) are used in the present study the screening dependence of the phonon frequencies in the equiatomic liquid alkali binary alloys. The pseudo-alloy-atom (PAA) model is applied for the first time for the alloying elements.
