Cavity-Induced Interference Pattern with Dark Center from Two Fluorescing Atoms

We show that the resonance fluorescence from a symmetric system of two incoherently pumped atoms coupled to a cavity mode produces interference fringes that possess a minimum on the symmetry plane. This unique deviation from Young-type interferences can be explained intuitively by the process of stimulated emission and reabsorption, leading to a cavity-induced anticorrelation of the atomic dipoles. Detailed consideration of an optical pumping scheme reveals the surprising role of cavity damping. We propose an experiment utilizing a two-level system in ${\mathrm{In}}^{+}$.
