Monitoring the dipole-dipole interaction via quantum jumps of individual atoms - art. no. 053803

The emission characteristics in the fluorescence of two laser-driven dipole -dipole-interacting three-level atoms is investigated. When the light from both atoms is detected separately a correlation of the emission processes i s observed in dependence of the dipole-dipole interaction. This opens the p ossibility to investigate the dipole-dipole interaction through the emissio n behavior. We present quantum Monte Carlo simulations which are in good ag reement with the analytic solutions.
