Abstract

The quantum properties and amplitude-squared squeezing effects of light field are studied in the system of two-mode SU(1,1) coherent states interacting with Bose-Einstein Condensate of V-type three-level atoms,and the squeezing properties of atomic laser have also been discussed.The results show that the quantum correlation properties of light field keep invariant in the process of interaction between light field and atomic BEC,and the photons of each mode produce antibunching effect.The correlation between the two modes shows the non-classical correlation in the process of interaction.There are amplitude-squared squeezing effects in these quantum states.The influence of field parameter and atom parameter on the depth and duration of squeezing are investigated.The two-mode atomic laser can be squeezed,but it is difficult to squeeze.The degree of squeezing is determined by initial light field.

The squeezing properties in the system of two-mode SU (1, 1) coherent states interacting with Bose-Einstein Condensate of two-level atoms

Lei Wang, Sun Chang-yong

The squeezing properties of optical field and atomic laser are studied in the system of two-mode SU (1, 1) coherent states interacting with two-level atomic BEC. The results show that two quadrature components of optical field can be squeezed periodically. The frequency of squeezing of optical field depends closely on both the interaction among atoms in BEC and the coupling constant between optical field and atoms. The maximum depth of squeezing is closely correlated to the two-mode SU (1, 1) coherent states parameters. The two quadrature components of atomic laser also can be squeezed, but it is difficult to squeeze. The maximum depth of squeezing is determined by the initial optical field.

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.

?The quantum correlation properties of two-mode squeezed field interacting with Bose-Einstein condensate of V-type three-level atoms are studied. The results show that the quantum correlation properties of light are determined completely by initial field and keep unvariant in the process of interaction between light field and atomic BEC.

Squeezing properties of two-mode atom laser in a system of Ξ-type three-level atomic Bose-Einstein condensate interacting with single-mode light field

Nong Chun-Xuan, Ming Li, Chen Cui-Ling

The squeezing properties of the two-mode atom laser in a system of Ξ-type three-level atomic Bose-Einstein condensate interacting with single-mode squeezed coherent light field are studied. The results show that the two-mode atom laser can be squeezed periodically, and has two types of oscillations: quantum Rabi oscillation and collapse-revival oscillation. The maximum depth of squeezing and the collapse-revival frequency of the atom laser depend greatly on the interaction intensity between the light field and atoms, and the quantum Rabi frequency is largely determined by the frequency of the light field.

Squeezing properties of two-mode squeezed field interacting with V-type three-level atoms

Ming Li, Tao Tang, Ding-Han Chen

The Hamiltonian operator of a system of V-type three-level atomic Bose-Einstein condensate interacting with two-mode squeezed coherent light field is analyzed in terms of the lattice-liquid model. It is indicated that the contribution of the interaction between atoms to the Hamiltonian in the literature is unreasonable,so the Hamiltonian operator is improved and the squeezing properties of two-mode squeezed field interacting with V-type three-level atoms are studied. The results show that two quadrature comonents of light can be squeezed periodically and that maximum depth of squeezing is closely related to the initial squeezing parameter of light and that the duration is determined by the frequency of two-mode field.

Properties of Field in the Interaction Between V-type Three Level Atoms and Nonclassical Light

Zhifang Feng, Xiuping Li

When neglecting and considering the interaction between atoms,the quadrature squeezing and the photon-number squeezing of Bose-Einstein Condensate of V-type three level atoms interacting with two-mode squeezed light field are studied.The results show that the quadrature squeezing dependent on squeezing parameter and the photon-number squeezing is closely correlated to squeezing parameter and light field intensity.It is found that the two kinds of squeezing can be obtained at some conditions.and the interaction between atoms in BEC changes the period of fluctuation of light field and the amplitude of fluctuation of quadrature component.However,such atom-atom interaction does not affect the amplitude of fluctuation of photon-number squeezing.
