Dipole amplitude-squared squeezing of a moving Ξ-type three-level atom in the binomial states field

Abstract

Abstract:

The atomic dipole amplitude-squared squeezing effects of a Ξ-type three-level atom interacting with the binomial states field were studied by solving Schrödinger equation and numerical calculation. We analyzed the effects of the optical field parameter, the field-mode speed, the -parameter, and the optical field and atomic coupling coefficient on the atomic dipole amplitude-squared squeezing effects. The results indicate that, with the optical field parameter increasing, the atomic dipole amplitude-squared from does not have compresses to presents the periodic squeezing, the squeezing depth deepens gradually.Increases along with the field-mold speed, the atomic dipole amplitude-squared from squeezing incompletely to squeezes completely. Increase along with the -parameter the atomic dipole amplitude-squared does not compress to the periodic squeezing, finally it does not squeeze. The optical field and the atomic coupling coefficient do not affect an atomic dipole amplitude square squeezing.

Key words: quantum optics, amplitude-squared squeezing, the binomial states field, a moving three-level atom
