From: Giant frequency down-conversion of the dancing acoustic bubble
Oscillation power spectrum of a bubble in a chain of bubbles calculated as the Fourier transform of the normalized time-autocorrelation function of the position of the bubble (lower inset).
Top inset: position of the center of the bubble normalized to half a wavelength of the acoustic standing wave as a function of time. Right: snapshot of a segment of a chain of bubbles. Data is reported for the central bubble.
