Extended Data Fig. 3: The residual 50 Hz noise and Rabi oscillations between the |3⟩ and |4⟩ hyperfine levels.
From: Observation and quantification of the pseudogap in unitary Fermi gases
a, The data points (red circles) are obtained by measuring the resonant frequency of the |3⟩ to |4⟩ microwave transition as a function of delay time td, i.e., the time duration between the synchronization trigger and the microwave pulse. The red solid line is the sine fitting curve with 50 Hz frequency. The red arrow indicates the moment of the synchronization trigger. b, Data points: the normalized atom number in level |4⟩ as a function of microwave duration. Every data point corresponds to an average value of approximately 10 independent measurements. The error bar represents one standard error. The solid line is the fitting curve described by equation (3).
