Abstract

The atomic dipole amplitude-squared squeezing effects of a Ξ-type three-level atom interacting with two-mode entangled coherent states are investigated.The effects of the degree of entanglement of the two-mode entangled coherent states,the ground state probability amplitude of the atomic initial state,the detuning,the mean photon number and the atom-field coupling constant on the atomic dipole amplitude-squared squeezing are analyzed.The results indicate that the light squeezing effects depend on the degree of entanglement of the two-mode entangled coherent optical fields,the detuning,the mean photon numbers,the atom-field coupling constant and the atomic initial state.

The atomic dipole squeezing effects in the system of a two-mode entangled states interacting with a Σ-type three-level atom were studied.We analyzed the effects of the degree of entanglement of the two-mode entangled coherent states,the ground state probability amplitude of atomic initial state,the detuning,and the mean photon numbers on the atomic dipole squeezing effects.The results indicate that the influence of the(degree) of entanglement of the two-mode entangled coherent states on the atomic dipole squeezing effects isn't noticeable.While the atomic initial state is in the ground state or excited state,the atomic dipole squeezing effects can not occur.While the probability of atomic initial state in ground state is equal to that in the excited state,the atomic dipole squeezing reaches its maximum.The enhancing of the detuning results in the increase of the frequency of atomic dipole squeezing.When the mean photon number of mode 1 remains unchanged and the mean photon number of mode 2 increases,the depth of atomic dipole squeezing decreases and the(frequency) of atomic dipole squeezing doesn't change.

Atomic dipole amplitude-squared squeezing in the coupling system of a three-level atom with radiation field

Zhu Cong

This paper studied the atomic dipole amplitude squared squeezing in the system of a three level atom interacting with a single mode radiation vacuum field. Numerical method is adopted to discuss the influence of the relative value of atom field coupling constants and the atomic initial coherence on the squeezing effect. It is found that no squeezing is produced in the process of interaction if the atom is initially most excited or in its ground state. However, if the atom is initially in a coherent superposition state of the ground state and the most excited state, there will be dipole amplitude squared squeezing effect in the process of interaction; the squeezing degree depends on the phase factor relating to atomic initial coherence; when other conditions are fixed, the atom will produced optimum squeezing effect if the probability of atom initially in the most excited state is 1/4 and the probability of it initially in the ground state is 3/4. If none of the atom field coupling constants are zero, the quantities of squeezing vary periodically; the change period of the quantities of squeezing depends on the relative value of two atom field coupling constants.
