(a) VAFs for three groups of Cu atoms. Inset: the vibration density of states obtained by Fourier transform of VAFs. (b) Bottom panel: the Lindemann parameter of Cu atoms with different activated times. The inset: the typical trajectories of Cu atoms with N a = 0 and N a = 22, respectively. Scale bar: 0.5 Ǻ. Top panel: atomic configuration taken from the initial structure, illustrating the liquid-like FUs embedded in solid-like elastic matrix in MGs revealed by our analysis.
