a Measured phase diagrams with forward scanning from U = 3.5 V to U = 4.5 V and vice versa. b Measured frequency of the dominant peak versus voltage U from (a). The blue data represents the forward scanning case and the orange data corresponds to the backward scanning case. There is a hysteresis loop that indicates the relationship between the voltage U applied to the Rydberg atoms and the resulting dominant peak in the Fourier spectrum of the probe transmission. c Fourier spectra for U = 3.8 V (blue) and U = 4.3 V (orange).
