Radiation squeezing effect in the system of the squeezed vacuum field interacting with a moving two-level atom

Abstract

The radiation squeezing effect in the interaction process between the single mode squeezed vacuum field and a moving two-level atom is studied by means of solving the Schrdinger equation and numerical calculations.The results are as follows: with the increasing of the atom's speed and the parameter of field model structure,the time evolution curve rises noticeably;with the rising of the probability breadth of the atom ground state,the squeezing depth of the radiation field increases,otherwise it decreases,even there is no squeeze;the phase angle effects the time evolution curve's change like the probability breadth of the atom ground state;during the process that the compression factor becomes larger,the radiation field can not squeeze firstly,then it squeezes partially,finally the squeeze gradually disappears.

RADIATION SQUEEZING OF THE SYSTEM OF THE COHERENT STATES FIELD INTERACTING WITH A MOVING -THPE THREE-LEVEL ATOM

Gui Chuan-you

By means of solving the Schrodinger equation and numerical calculation,the radiation squeezing effects in the system of the coherent states field interacting with a moving-type three-level atom has been discussed.The numerical result indicates that,in the system of the coherent states field interacting with a moving-type three-level atom radiation field,mean photon number,the speed of motion atom and the field mold structure would have the certain degree of influence on the radiation squeeze.When fixed the speed of moving atom and the field mold structure,through increases the mean photon number may realize completely complete squeezing effects.Along with increment of mean photon number,there is no change in the oscillation period of the squeezing curve,but its scope increases obviously and its stability begins to reduce;when the mean photon number and the field mold structure fixed,the speed of moving atom has a great infection on the extent and period of the radiation squeeze.With the speed of moving atom increasing,not only the complete squeezing effect would be archived,the stability would also enhance.

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.
