The statistic properties of photon in the system of two-mode entangled coherent field interacting with two two-level atoms via multiphoton process are investigated by means of quantum theory and numerical method.The effect on statistic properties of photon induce by the mean photon number of field,the absorbing or emitting photon number,the degree of the entanglement for the entangled coherent field,and the coupling strength of dipole-dipole interaction between atoms are discussed.

The statistic properties of photon of a light-atoms interaction system,and two atoms in Bell states interacting with two-mode entangled coherent field,were investigated by means of quantum theory and numerical method.The effect on the statistic properties of photon induced by the atomic initial state,mean photon numbers of field,the degree of the entanglement for the entangled coherent fields,and the coupling strength of dipole-dipole interaction between atoms were analyzed by numerical calculations.The results indicate that photon anti-bunching effect does not appear for the Bell state ｜β00〉 or ｜β10〉,however there can appear the photon anti-bunching effect under some conditions for the Bell state ｜β01〉 or ｜β11〉 appears.In the case,the photon anti-bunching effect depends on the mean photon numbers intensively.The influence of the degree of entanglement for the two-mode entangled coherent fields and the coupling strength of dipole-dipole interaction between atoms on the statistic properties of photon is small.

The statistic properties of photon in the system of the two-mode odd-even entangled coherent optical field interacting with a V-type three-level atom are investigated by mean of Schrdinger equation solution and numerical calculations.The results indicate that the statistic properties of photon depend on the degree of entanglement of the two-mode odd-even entangled coherent optical fields,the detuning,mean photon numbers and atomic initial state.
