In this article,the second-order coherence properties of light in the system of two identical two-level entangled atoms Raman interacting with the coherent optical field are studied by means of the quantum theory and the numerical method.
In this article,the squeezing properties of light in the system of two identical two-level entangled atoms Raman interacting with the coherent optical field are studied.The results obtained by numerical method show that light squeezing effects depend on the mean photon numbers of the coherent optical field and the degree of entanglement of the initial two identical two-level entangled atoms,with the increasing of the degree of entanglement of the initial two entangled atoms,the average value of the fluctuation of two quadrature components of light decreases and the squeezing time is prolonged.
In this article, the quantum properties of light field of the two identical two-level entangled atoms interacting with the binomial optical field were studied by means of time evolution operator and numerical calculations. The results show that the time evolution of the squeezing and coherence properties of the light field depends on the entanglement degree of the initial two identical two-level entangled atoms and the parameters of the binomial optical field. The optical field fluctuation can be completely squeezed via choosing appropriate parameters.
