摘要：

A new method to calculate the phonon dispersion relations is presented in this paper. By using the Mobius-converted pair potential and a simplified three-body potential the phonon dispersion relations are calculated in three directions with a very simple procedure. The results for copper are in good agreement with experiments. Of more importance, it indicates the potential application of the Mobius method to different physical problems.
