“…(17), the coefficients in Eq. (8) can be derived with the help of the secular approximation [38], and we have It should be noted that here we take into account only the sideband transitions of the dressed atoms and neglect the central-peak transitions since the expressions from these processes are very complicated, and moreover, they contribute little to the entanglement of the cavity field for the case δ γ j [32,34].…”

“…Theoretically, a number of proposals for producing CV bichromatic entanglement via NFWM in atomic systems have also been put forward in Refs. [30][31][32][33][34][35][36]. For example, it shows that two-color highly entangled light beams can be generated via NFWM from N intracavity three-level atomic system close to electromagnetically induced transparency [37].…”

In this paper, we investigate the generation of polychromatic quadripartite entanglement of continuous variables from a three-level -type atomic system inside an optical quadruply resonant cavity. The atoms are driven by external lasers and simultaneously coupled to four cavity modes by means of multiply concurrent four-wave mixing interactions. The general master equation of the cavity field is derived explicitly. By solving the Gaussiantype master equation and using the negative-partial-transpose criterion for bipartite entanglement, we show that the genuine quadripartite entanglement of the field can be generated over a wide range of parameters. The entanglement properties of the four-mode field are discussed in detail. We find that the optimal quadripartite entanglement can be obtained when the cavity modes are tuned to be resonant with the Rabi sidebands of the driven atoms.

“…The ladder system was experimentally studied using a 85 Rb atom beam, which showed the narrowing of the central peak and reminding the spontaneously generated coherence phenomenon in a V-type system responsible for such narrowing [16]. Likewise, a two-mode-entangled light generation from a laser-driven, three-level V-type atom kept inside a cavity was 2 reported, where the spontaneously generated quantum interference between two atomic decay channels played a crucial role [17]. In reality, there is continued interest to generate SGC in cavity QED.…”

“…The effect is usually referred to as spontaneously generated coherence (SGC) or vacuum induced coherence (VIC). Subsequently, various remarkable effects based on SGC have been presented in threelevel atomic systems such as coherent population trapping [8], lasing without inversion [9], ultrafastall-optical switching [10], dark-state polaritons [11], optical bistability and multistability [12] and quantum information and quantum computing [13,14]. More recently, people have paid a great deal of interest to the interference effects in multi-level systems due to the fact that extra quantum interference possibilities are induced by the additional levels.…”

The fluorescence photon correlations in a driven four-level atom consisting of three upper closely lying excited states and a single lower state are investigated. It is found that in the presence of triple spontaneously generated coherence (SGC) effects, which are created by three degenerate levels coupling to the common ground state via the same vacuum mode, the correlation properties of the three fluorescence fields can be switched from strong correlation to anticorrelation or vice versa by modifying the detunings. In addition, such a system is very sensitive to the relative phases of the three fields, which can provide an effective way to control the photon correlation. Physically, these interesting phenomena can be interpreted in terms of dressed state analysis.
