Continuous time crystal in an electron-nuclear spin system: stability and melting of periodic auto-oscillations

Abstract

Extended Data Figure 4. Magnetic field dependence. a, Time series measured at different angles α for fixed Bx = −1 mT. Ppu = 0.3 mW, Ppr = 1 mW. b, Time series measured for fixed angle α = 7 • and at different strength of the magnetic field. Both Bx and Bz are varied. Ppu = 0.3 mW, Ppr = 0.05 mW. c and d are the corresponding Fourier transform spectra. T = 6 K.
