Summary:
In this study, we investigate nonlinear vibration modes of an atomic system which consists of six particles. The nonlinear vibration modes are continued from phonon modes of the system. Relation between frequencies and amplitude are discussed. Linear stability of the nonlinear vibration modes is also analyzed. It is found that, in some range of initial amplitude, energy exchange is observed between a few vibration modes.
