Abstract

In this paper,we have studied the photon bunching and anti bunching effects in the process of squeezed coherent state interacting with a three level cascade atom inside a high Q cavity filled with a Kerr medium.The influences of the field parameters and the Kerr medium on the photon bunching and anti bunching effects have also been discussed.

INFLUENCE OF KERR EFFECT AND VIRTUAL PHOTON FIELD ON THE PHOTON ANTI-BUNCHING OF INTERACTION BETWEEN FIELD AND ATOM

TAO XIANG-YANG, Liu San-qiu, Yi-you Nie +2 more

We have studied the interaction between a cascacle three-level atom and the cavity field filled with Kerr medium by C-RWA. The influence of Kerr effect and virtual photon field on the photon anti-bunching is discussed. The results show that the quantum noise appears under C-RWA; the increase of x and ω or the decrease of g leads to the decrease of absorbance of atom and the reduction of photon antibunching;especially,the interaction is influenced obviouslly by g.

Atomic Population in the System of the Three-Level Cascade Atom Interacting with Squeezed Coherent Light Field in a Kerr Medium

Liu Su-mei

In this paper, the atomic population evolution vs. time in the system of three-level cascade atom interacting with squeezed coherent light field in a Kerr medium is investigated by means of the interacting picture and the quantum theory. Meanwhile, the influence of Kerr medium μ, the squeezed light field factor γ and the coherent vibration amplitude |α| 2 of the field-atom on the atomic population is also discussed. It has been shown that the intensity coefficient μ of Kerr medium, the squeezed light field factor γ and the coherent vibration amplitude |α| 2 of the light field influence the quantum collapse-revival periodicity of the evolution curves of atomic population directly. And the non-linearity Kerr medium μ can weaken the interaction of the atom with the field. When Kerr medium μ and the interaction of the field-atom increase to a certain value, the correlation degree of light-field and atom will weaken and disappear.

Effects of Kerr medium on two-mode field squeezing

Zhang Li

The field squeezing in the system of a three level atom embedded in a high Q cavity filled with Kerr medium is investigated.The effects of Kerr medium on two mode field initially in two mode squeezed vacuum state and SU(1,1) coherent state are analyzed.It is found that the influence of squeezing for the field initially in SU(1,1) coherent state is more evident that for the field initially in two mode squeezed vacuum.
