| Abstract Scope |
The present paper deals with the theoretical study of the vibrational modes and elastic properties of Zr₆₁CuₓNi₁₂.₈Al₇.₉Sn₁₋ₓ bulk metallic glass using our well-defined pseudopotential. Phonon dispersion curves for both longitudinal and transverse modes are computed using the Hubbard-Beeby (HB) and Takeno-Goda (TG) approaches. The influence of electronic screening is analyzed through four local field correction functions: Hartree (H), Ichimaru-Utsumi (IU), Farid et al. (F), and Sarkar-Sen et al. (S). The calculated phonon spectra reproduce key features of vibrational dynamics, while the elastic constants show good agreement with experimental data. This work highlights the critical role of screening effects and validates the reliability of our pseudopotential framework for modeling complex amorphous alloys. |
