a Dynamics of Mx along the upper track as a function of time for a periodic state as an enlarged view of Fig. 1a. b Fast Fourier transform (FFT) of the temporal evolution of Mx(x, t) at each spatial position from panel (a), transforming the time-space data into frequency-space. Periodic nodes are observed in both time and position. c Mean value of Mx along the upper track as a function of time, showing the stability of the dynamics in the periodic state. d FFT of the mean value of Mx, indicating global periodic behavior. e Enlarged view of Mx for the chaotic state in Fig. 1b. f FFT of Mx in panel (e), showing a broad spectrum of frequencies characteristic of chaotic dynamics. g Mean value of Mx as a function of time for the chaotic state, highlighting the complexity of the dynamics. h FFT of the mean value of Mx, revealing the broad frequency spectrum typical of chaotic states.
