Light-induced correlations in spontaneous emission

Frequency-resolved Monte Carlo

“…6 . In the case of resonance fluorescence, such correlations have been noted by Apanasevich and Kilin 53 for the case (that is, overlooking the counterparts, which are equally obvious with the dressed atom picture in mind). Interestingly, part of this school of researchers, who has produced noteworthy works on the problem of photon correlations 54 – 56 , has recently expressed some critics on this leapfrog picture, writing that 28 “ the concept of the “leapfrog” processes is not justified ”, that they “ present an alternative explanation ” based on “ the unnormalized spectral correlation function ” which is, they write, “ a true measure of spectral correlations ” and “ which exhibits no signatures of the leapfrog transitions ”.…”

Correlation functions in resonance fluorescence with spectral resolution: Signal-processing approach

“…However, the expression for the frequency resolved field correlation function in [44] differs from that given by Eq. (8) and rather corresponds to the spectral decomposition performed by a prism [43].…”

“…To characterize spectral correlations in RF, instead of g (2) Γ (δ 1 , δ 2 ; 0) we will use the unnormalized function [8] ∆G (2)…”

“…lated pairs thereof. It was predicted in [8] that in the limit Γ → 0 the sideband photons satisfying the condition ω 1 + ω 2 = 2ω L are strongly correlated, but the function (32) has not been systematically studied.…”

“…The RF spectrum provides information about the elementary scattering processes of laser photons on the atom. The identification of the scattering processes that are correlated requires a study of higherorder spectral correlation functions [8].…”
