Transition from antibunching to bunching for two dipole-interacting atoms
Almut Beige, Gerhard C. Hegerfeldt · Physical Review A · 1998
It is known that there is a transition from photon antibunching to bunching in the resonance fluorescence of a driven system of two two-level atoms with dipole-dipole interaction when the atomic distance decreases and the other parameters are kept fixed. We give a simple explanation for the underlying mechanism that in principle can also be applied to other systems.
