Resumo

This paper studies a system that contains various atoms coupled by dipole-dipole interaction. The fluorescence spectrum and the dressed energy levels are calculated by a new method. It first solves the problem for two different spatial configurations of three coupled two-level emitters. Then, it is shown that the coupling among dressed levels and consequently energies and number of sidebands in the fluorescence spectrum differs in the two configurations. Accordingly, the fluorescence spectrum can serve as a tool to give information about the interaction and configuration of atoms. In addition, to study the fluorescence spectrum, the Bogoliubov-Born-Green-Kirkwood-Yvon approximation is used, and the accuracy of this approximation is analyzed for the different sizes of the system. It is proven that this approximation is suitable for studying the fluorescence spectrum for a weak dipole-dipole interaction, which occurs when the distance between the emitters is comparable to or larger than the optical wavelength.
