Antibunching Effect of Field in Non-resonant Interaction Between Entangled Double Atoms and Coherent Field

By using the fully quantum theory and the numerical calculation, the field antibunching effects were studied when the coherence fields interacted non-resonant with the entangled double atoms in the dissipative cavity. The influence of the initial mean photon numbers, the detuning of atom and field, the cavity damping rates on the field antibunching effects were disscussed. The results showed that the initial mean photon numbers significantly affected the antibunching effect of the field. If the initial field was weak, the bunching and antibunching occured in turns caused by the atom-field detuning. As the detuning increased, the time of antibunching effect was expanded and the negative correlation increased obviously among photons. However, the non-classical pro- perties trended to vanish as the decay rates increased in cavity.
