Abstract:

The dipole difference squeezing of a pair atoms is definited. 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. Using the numerical method, the influences of the initial squeezing parameter of light, the atomic initial state and the intensity of dipole-dipole interaction between atoms on the squeezing properties of atom and light are discussed.

Key words: quantum optics, dipole difference squeezing of a pair atomis, amplitude-squared squeezing of light, quantum theory, dipole-dipole interaction
