Abstract
Computations of the frequencies of the longitudinal and transverse phonon modes in a quaternary bulk metallic glass (Cu60Zr20Hf10Ti10) based on a simple model approach have been presented. The model assumes a central force, effective between the nearest neighbours and a volume dependent force. Both types of excitations of phonons are computed for the bulk metallic glass for the first time both for self-consistent screening of conduction electrons with and without the inclusion of correlation effects. Phonon frequency expressions reproduce the main characteristic features of the dispersion curves.
