Time-Oscillating Lyapunov Modes and the Momentum Autocorrelation Function
Time-Oscillating Lyapunov Modes and the Momentum Autocorrelation Function
The Lyapunov vectors corresponding to the steps of Lyapunov spectra for many-particle systems show time-oscillating behavior in two types of Lyapunov modes, one associated with time-translational invariance and the other with spatial translational invariance. Our result is that, for each coordinate direction, the longest period of the Lyapunov modes is …
