摘要: Amplitude and phase synchronization due to multiscale interactions in chaotic saddles at the onset of permanent spatiotemporal chaos is analyzed using Fourier-Lyapunov representation. By computing power-phase spectral entropy time-averaged spectra, we show that laminar (bursty) states on-off intermittency correspond, respectively, nonattracting coherent structures with higher (lower) degrees amplitude-phase across spatial scales.
