Fig. 4: Phase transition between distinct time crystals.

a Phase diagram of a voltage range from U = 975 mV to U = 990 mV in a high resolution. The black dashed line represents the modified Heaviside fitting function. The color bar from 0 to 1 represents the Fourier transform intensity. b–d Corresponding Fourier spectra at U = 978.75 mV (b), U = 982.5 mV (c), and U = 986.25 mV (d). The phase diagram includes two temporal periodicities called the LP and the SP, which are separated by the white dashed line. In the SP time-crystal phase, the temporal order is the shorter-range order, which means that the system’s response is repeated periodically over shorter time intervals. In the LP time-crystal phase, however, the system’s response is repeated periodically over longer periods of time.
