Resonance fluorescence in a many-atom system

Abstract
We present in this paper a new method, wave-function recoupling in a many-atom system, in solving the resonance fluorescent spectrum. For a two-atom system, if the influence of stimulated emission on the cooperative effect is taken into account, the resonance fluorescence spectrum is expected to display five peaks. For a frequency-detuning case, an obvious asymmetry may appear in the spectral intensity distribution.
