“…One consequence of this is a possible modification of the resonance fluorescence spectrum of the atom allowing e.g. for quantum beat oscillations [4], dark states [5,6], macroscopic dark periods [7,8] or very narrow resonances [1,6,9,10]. The atomic three level system may also be in Λ-configuration [12].…”

“…It is well known that an atomic three-level system in V-configuration driven by laser fields gives rise to many interesting quantum optical effects [1][2][3][4][5][6][7][8][9][10][11]. If the two atomic upper states are closely-spaced such that the two transitions to the ground state interact with the same vacuum modes, quantum interference may occur.…”

We discuss quantum interference effects in a three-level atom in Λ-configuration, where both transitions from the upper state to the lower states are driven by a single monochromatic laser field. Although the system has two lower states, quantum interference is possible because there are interfering pathways to each of the two lower states. The additional interference terms allow for interesting effects such as the suppression of a dark state which is present without the interference. Finally we examine a narrow spectral feature in the resonance fluorescence of the atom with quantum interference.

“…However, in this case the two side peaks for df 0 disappear towards df p. Obviously, in the case when V , and df p there is no net field applied to the atom. Then, the atom will remain in the ground state if it is initially in the ground state or will behave as Agarwal [2] and others [3,20] described if it is initially in a superposition of the two excited states. Furthermore, in Fig.…”

The dynamics of an atomic few-level system can depend on the phase of driving fields coupled to the atom if certain conditions are satisfied. This is of particular interest to control interference effects, which can alter the system properties considerably. In this article, we discuss the mechanisms of such phase control and interference effects in an atomic three-level system in Λ configuration, where the upper state spontaneously decays into the two lower states. The lower states are coupled by a driving field, which we treat as quantized. This allows for an interpretation on the single photon level for both the vacuum and the driving field. By analyzing the system behavior for a driving field initially in non-classical states with only few Fock number states populated, we find that even though the driving field is coupled to the lower states only, it induces a multiplet of upper states. Then interference occurs independently in three-level subsystems in V configuration, each formed by two adjacent upper states and a single dressed lower state.
