Resonance fluorescence of an adatom near solid surfaces

By using the reservoir theory and Dekker's quantization procedure for a dissipation system, a set of new surface-dressed optical Bloch equations including the surface-induced frequency shift as well as the decay rate is derived to calculate the resonance fluorescence spectrum of an adatom near a bulk solid surface. A mediate layer composed of nonabsorbing dielectric is placed to separate the adatom and the bulk solid. The size and the dielectric effects of this layer are found to be as important as those effects from the bulk solid. These effects will be directly exhibited in the decay rates and the frequency shifts. The resonance fluorescence spectrum is discussed in different cases and is found to be strongly affected by the surfaces
