Abstract

The interaction between two identical two-level atoms and single-mode binomial light field is studied in anti-Tavis-Cummings model,and the atoms stay in entangled state initially.When the classical field is strong enough,the interaction between the atoms and the light field can turn into an effective anti-Tavis-Cummings model and Tavis-Cummings model under the condition of large detuning.In this paper,we mainly probe into the squeezing property of the binomial state in anti-Tavis-Cummings model,and the influence of initial field parameters on the squeezing property of the field are discussed.The results show that the degree and period of squeezing depend strongly on the initial parameters,and energy nonconservation item has a great impact on squeezing property.

The field entropy evolution of two moving atoms interacting with the binomial field in Tavis-Cummings model is studied by means of the quantum theory.The influences of atomic motion and the parameters of the binomial optical field under different initial states are discussed emphatically.With the increase of the parameters of the binomial optical field,the entanglement degree between field and atoms is strengthened firstly and is weakened later.When the field is in the middle states,And as the speed of the moving atoms increases,the atom-field system will stay in the maximum entangled state.the entanglement degree between the field and atoms is weaken and the periodicity of the evolution of the field entropy decreased.When the field is in the middle states and the atoms is at the lower speed,the entanglement between the binomial field and the two atoms can be kept for much longer time.

The Atoms's Entanglement Character of Two Entangled Atoms Interacting with the Binomial Light-Field in the Multiphoton Tavis-Cumming Model

Li Bao

The entanglement character of two entangled atoms interacting with the binomial light-field in a multiphoton Tavis-Cumming model(T-C model) is studied by means of the quantum theory.The influences of the optical field parameters and the atomic dipole-dipole coupling intensity of the atoms on the properties of the entanglement between two atoms under different initial states are discussed.The results indicate that the periodicity of the entanglement between two atoms is influenced by the parameters of the binomial optical field.There are the entanglement phenomena at some values of nπ except the value of 5nπ(n=0,1,2,…).With the increase of the parameters of the binomial optical field,the range appearing entanglement phenomenon will increase gradually.Thereby the time in that the entanglement between the two atoms occurs will diminish.The atomic dipole-dipole coupling intensity has an effect on oscillating of entanglement and the entanglement degree between the two atoms.

The atoms′ entanglement character of the moving atoms in tavis-cummings model with the binomial field interacting is studied.The results indicate that the two moving atoms entanglement state appears periodically.The influences of the atomic motion and the parameters of the binomial light field on the atoms′ entanglement character are discussed by means of the full quantum theory.The parameters of the binomial optical field has an effect on the entanglement、the frequency of oscillating and the range appearing entanglement phenomenon,but it does not influence periodicity of the entanglement of the evolution.The two atom′s speed influence the periodicity of the entanglement of the evolution in the middle state of the optical field.The atom′s speed does not influence the value of the entanglement and the frequency of oscillating of the atoms.

Quantum properties of light field of two identical two-level entangled atoms interacting with radiation fields in binomial states

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.

Quantum properties of the binomial states field interacting with a Λ-type three-level atom

Cui Ying-hua

The quantum properties of light in the system of Λ-type three-level atom interacting with radiation fields in binomial states are studied by means of quantum theory.The influences of the initial states of the Λ-type three-level atom and the parameter of the binomial optical fields on squeezing of the optical field and the second-order coherence degree are investigated in detail.As the detuning parameter of atom A and the parameter of the binomial optical fieldηare small,bunching and antibunching effect can be exhibited alternatively.With the increase of the parameters,the light field shows antibunching effect completely.If the detuning parameter of atomΔand the parameterηare chosen appropriately, the component X_1 of the light field in the coupling system will be squeezed during the certain time.The results indicate that the light field shows squeezing effects and continuous antibunching effect under a certain condition as it interactes with a A-type three-level atom.

Quantum properties of atomic:laser in system of binomial states field interacting with Bose-Einstein condensate of two-level atoms

Sun Chang-yong

The quantum correlation properties and squeezing properties of atomic laser are studied in the system of the binomial states field interacting with Bcse-Einstein condensate of two-level atoms,and the amplitude-squared squeezing effects of atomic laser are also discussed.The influence of field parameter and atom parameter on the depth and duration of squeezing are mainly investigated by solving the Heisenberg equation based on the entire quantum theory.The results show that the quantum correlation properties of atomic laser keep invariant in the process of interaction between light and atomic BEC.The two quadrature components of atomic laser evolve periodically with t(?)me and can be squeezed.The depth of squeezing is determined by the binomial states field.The duration of squeezing depends on the coupling constant between light field and atoms.The relations and differences are briefly discussed between the squeezing effects and amplitude-squared squeezing effects.
