When recording quantum states at a ﬁxed scaled energy ˜E as a function of the scaling parameter w = F −1/4 , each isolated closed orbit contributes a sinusoidal modulation to the sum (2), which can be extracted by a Fourier transform of the quantum spectrum.

In the case a. the observed dynamics is clearly sinusoidal oscillations with the predicted amplitude and period.
Rabi spectra - a simple tool for analyzing the limitations of RWA in modelling of the selective population transfer in many-level quantum systems
In the ﬁrst case, the coupling is relatively weak so that the condition (12) is fully satisﬁed (actually, Γ = 50) and the pure sinusoidal population oscillations are observed.

In Sect. 3 we show the behavior of the Fourier Transform (FT) in the case of an absorbed sinusoid.
A simple model for the complex lag structure of microquasars
If we compute the Fourier Transform of a sinusoid function we obtain the frequency, amplitude and phase.
A simple model for the complex lag structure of microquasars
We see that by doing the FT on this signal we obtain different parameters for the sinusoid.
A simple model for the complex lag structure of microquasars
This comes from the fact that the FT adjusts the data with a shifted sinusoid, creating a phase difference.
A simple model for the complex lag structure of microquasars
The ﬁrst way to check this idea is to look at the QPO proﬁle and see if there is an energy dependant departure from a sinusoidal signal.
