To normalize the curves in Fig. (3), Fig. (4) and in the following section, we use the back scattering current to zero order in the amplitude of ω$_{1}$ of the modulation wich corresponds to the pure stationnary regime$^{30}$: In this section, we display curves for the charge correlator at equal times. We consider excess quantities. By excess, we mean that the charge correlator at zero voltage has been subtracted from the charge correlator at V$_{0}$, V$_{1}$ = 0 . In Figs. 5, 6, 7 and 8 we plot these quantities: B. Measured PA noise I (0) B = e ∗ Γ 2 0 2 π $^{2}$a$^{2}$Γ(2 ν ) ( a ν$_{F}$ ) 2 $^{ν}$sgn( ω$_{0}$ ) | ω$_{0}$ | 2 $^{ν}$− 1 .

(52) with weak and strong dissipation, low and high (detector) temperature for two different values of the ratio ω$_{1}$/ω$_{AC}$ , which corresponds to the argument of the Bessel functions in the expression of the charge correlator. In the following curves Q − + is always normalized by L $^{2}$/ ( α $^{2}$e ∗ I$_{B}$ω 2 $_{0}$) and dissipation and temperature are in unit of ω$_{0}$ . The frequency Ω = ω$_{0}$ corresponds to the positions of the central peak. We start with ω$_{0}$ > ω$_{AC}$ . In order to resolve these peaks, it is necessary that the width of the resonance level is smaller than the spacing ω$_{AC}$ between peaks. We observe that by varying ω$_{1}$/ω$_{AC}$ , the relative amplitudes of the peaks can be modulated. In Fig. 6, the curves correspond to a ratio ω$_{1}$/ω$_{AC}$ = 2 : we can clearly identify the central peak at Ω = ω$_{0}$ but it is smaller than in the case ω$_{1}$/ω$_{AC}$ = 1 (in Fig. 5). In this situation we identify very clearly the fir st and the second satellite peaks, while the third one ( n = ± 3 ) is visible but with a lesser intensity. The relative amplitude of the central peak and its satellite is tied to the oscillatory behavior of the Bessel function. When ω$_{1}$/ω$_{AC}$ = 1 , the 0 th order Bessel function, which corresponds to the central peak has a large amplitude( ≈ 0 . 6 ). The 1 st order Bessel function which corresponds to the first satel lite peak, has a smaller amplitude ( ≈ 0 . 2 ). The third Bessel function which corresponds to the second satellite peak is almost zero. On the other hand for ω$_{1}$/ω$_{AC}$ = 2 , the 0 th and the 3 rd order Bessel function are small compared to its 1 st and 2 nd order counterparts, thus the central peak is smaller than the satellites. Next, we choose ω$_{0}$ < ω$_{AC}$ in Fig. 7 and 8. The finite frequency spectrum of charge fluctua tions does not seem to display any longer a central peak with equally spaced satellites. In Fig. 7, the curves correspond to a ratio ω$_{1}$/ω$_{AC}$ = 1 and in Fig. 8 the curves correspond to a ratio ω$_{1}$/ω$_{AC}$ = 2 . In Fig. 7, the curves have a central peak at frequency ω$_{0}$ , a secondary one at ω$_{0}$ + ω$_{AC}$ and a third one at ω$_{0}$ + 2 ω$_{AC}$ . However there appear peaks at frequencies − ω$_{0}$ + ω$_{AC}$ and − ω$_{0}$ + 2 ω$_{AC}$ : this corresponds to the satellites peaks of the negative frequency − ω$_{0}$ . We can explain this phenomena as the overlapping of two combs, centered at ± ω$_{0}$ . In Fig. 8, the curves exhibit the same phenomena but the peaks have different relative amplitude, which can again be explained from the argument of the Bessel functions. In these differents plots, we can see on the one hand the effect of dissipation wich reduces the noise and smoothes the
