Quantum Properties of Light Field Interacting with Two Different Atoms

Shou Zhang

The quantum properties of light in the system of two different atoms interacting with two-mode squeezing vacuum field are studied.The effect of the relative coupling constant(R=g1/g2) and initial squeezed parameter r on light squeezing effect and the photon bunching and antibunching are discussed.The numerical results show that vibration range of quantum fluctuation,the biggest squeezing depth and squeezing time and vibration amplitude of second-order coherence is affected by the initial squeezed parameter r.The variation of quantum fluctuation and second-order coherence versus time are affected by the relative coupling constant R.As a result,the squeezing time of quantum fluctuation,the time when light field is in non-classical states and the degree of photon antibunching are also affected by it,but to but it doesn′t have obvious influence on light squeezing depth.

Coherence Properties of Light Field Interacting with Two Different Atoms

Shou Zhang

The coherence properties of light in the system of two different atoms interacting with two-mode squeezing vacuum field were studied.The effect of the relative coupling constant (R=g1/g2) and initial squeezed parameter on the second-order coherence,mode-correlation properties and Cauchu- Achwartz inequality were discussed.The results show that when the initial squeezed parameter is smaller,the phone bunching and antibunching are appearing by turns,and the dgree of mode-correlation property is more stronger.When the initial squeezed parameter is bigger,the photons are appearing bunching and the degree of mode-correlation propertity is weaken.The variation of second-order coherence,mode-correlation properties and Cauchy-Schwartz inequality versus time is affected by the relative coupling constant R,but the relative coupling constant can′t change the non-classical properties of light.

The dipole difference squeezing of a pair atoms is defined. The time evolution properties of difference squeezing of atomic dipole and amplitude-squared squeezing of light in the system of a single-mode squeezing vacuum field Raman interacting with two coupled-atoms are studied by means of quantum theory.
