The schematic diagram of the scheme. Two identical dipole-coupled two-level atoms trapped in a single-mode high-finesse optical cavity, which is pumped by a coherent laser field with strength η. The two atoms experience the cooperative emission with the rate γ. The dipole–dipole interaction strength, individually spontaneous emission rate of the atoms, and the cavity decay rate are J, Γ, and κ, respectively. The transmitted photons are detected by a photon detector.
