Abstract
Driven nonlinear oscillators constitute a universal paradigm for understanding synchronization, frequency pulling, and frequency comb formation in nonequilibrium systems. Here, we realize such an emergent nonlinear oscillator in strongly interacting cesium Rydberg vapor, where coherent optical excitation, dissipation, and long-range interactions give rise to a driven-dissipative time crystal with intrinsic oscillation frequencies. Further, by externally driving the system with two RF fields under an RF heterodyne condition, with a beat frequency near the intrinsic time crystal frequency, we observe frequency pulling, the generation of intermodulation products, and the emergence of a frequency comb spectrum in the atomic coherence.Citation
