Abstract

The property of the optical field interacting with two identical entangled atoms is investigated, where the interaction between atoms and cavity mode is a highly detuned one. The effect of the system parameters on the property of the optical field is discussed via time evolution operators and numerical calculation. The result shows that, in this highly detuned system, the optical field cannot manifest squeezing effect under any system parameter.

The squeezing properties in the system of the coherent optical field interacting with two identical two-level atoms are studied via time evolution operator and numerical method . The results indicate that the squeezing of optical field depends on the degree of entanglement of two identical atoms. At certain particular time, for some special numbers of photons, optical field can be squeezed entirely in any entangled state of two atoms. In some cases, the optical fields can not be squeezed.

By means of numerical calculations,the squeezing property of the light field in the non-resonant system of two entangled atoms interacting with coherent field in dissipative cavity is studied.The effects of the detuning between the atom and cavity field,the initial field intensity,the decay of the cavity field on the light squeezing are discussed.The results show that when two entangled atoms interact with coherent field in the non-resonat system,light squeezing may occur,the squeezing degree has the periodicity with the time evolution.Also,the squeezing degree of light field becomes strong,the squeezing time increases,when the initial field intensity is adjusted appropriately.With the increase of the decay of the cavity field,the squeezing degree of light field gradually becomes weak,the squeezing time gradually decreases.

Song Jun, Zhuo‐Liang Cao

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.
