    "abstract": "The different behaviour of first order interferences and second order\ncorrelations are investigated for the case of two coherently excited atoms. For\nintensity measurements this problem is equivalent to Young\u0027s double slit\nexperiment and was investigated in an experiment by Eichmann et al. [Phys. Rev.\nLett. 70, 2359 (1993)] and later analyzed in detail by Itano et al. [Phys. Rev.\nA 57, 4176 (1998)]. Our results show that in cases where the intensity\ninterferences disappear the intensity-intensity correlations can display an\ninterference pattern with a visibility of up to 100%. The contrast depends on\nthe polarization selected for the detection and is independent of the strength\nof the driving field. The nonclassical nature of the calculated\nintensity-intensity correlations is also discussed.",
