Quantum Properties of Cascade Three-Level Atomic System

Nuaa Nanjing

Published Jan 1, 1995• 0 citations
OpenAlex

Abstract

The interaction of a cascade three-level atominitially in the low state with two initially coherent fields is .investigated by using the properties of Poissonian distribution and Taylor expansion for the means of the atomic level occupations and the photon numbers as well as the dipole moments. Compared with the results of the numerical computation, the analytical results represent more clearly the quantum effects of the system

Quantum properties of a three-level atom interacting with two radiation fields

Xiao-shen Li, Yue-nan Peng

The quantum-statistical model for a three-level atom interacting with two radiation fields is studied. The mean atomic occupations and photon numbers are obtained under different initial conditions of one coherent field and one chaotic field or both chaotic or coherent fields, with the atom in upper or lower states. Through numerical summation, it is shown that the effects of coherent sources and chaotic sources are different even for low intensities. Meanwhile the effects of detuning on this interaction are discussed.

Effect of squeezed light on the photon-number probability distribution and sub-Poissonian distribution in the cascade three-level Jaynes-Cummings model

Lu-Bi Deng, Songen Sun

Quantum-statistical properties such as the photon-number probability distribution and sub-Poissonian distribution are studied by considering the resonant interaction of two radiation fields, one of which is in a squeezed state with a cascade-structure three-level atom. It is noteworthy to emphasize that the direction of squeezing, i.e., the angle \ensuremath{\theta}, and the squeezing parameter r as well as the initial atomic state play important roles in the determination of the nonclassical behavior of the radiation field. At the same time we give a possible explanation for the effect of the ratio of the intensity of the two fields on the quantum-statistical properties.

ANALYTIC SOLUTIONS FOR COHERENT THREE-LEVEL J-C MODEL

Xiao-shen Li, Yue-nan Peng, (1)江西师范大学物理系; (2)南京大学物理系

The interaction of a three-level atom initially in the common upper state with two initially coherent fields is investigated. Approximate analytic solutions for mean atomic level occupations and photon numbers are given, which exhibit collapse, revival and initial oscillation period explicitly. These are compared with the results of numerical, calculation, they agree satifactorily.

A QUANTUM-STATISTICAL THREE-LEVEL CASCADE JAYNES-CUMMINGS MODEL

Xiao-shen Li, 江西师范大学物理系

A quantum-statistical model for a three-level cascade atom interacting with radiation fields initially in coherent states is presented. By means of numerical summation and saddle-point approximation, the expectation values of the atomic-level operators and the photon numbers are obtained and discussed, which reveals the phenomena such -as the twophoton transitions and the new collapse and revival.

Sub-Poisson Distribution of a Radiation Field in a Cascade Three-Level Atomic System

Song-Gen Sun, Daning Shi

In a cascade three-level atomic system, a parametric study of sub-Poisson or super-Poisson distribution of a stimulated field was performed. By numerical calculation and figures, we investigated the time evolution of the sub-Poisson distribution of a radiation field. We found that different atomic initial states and different ratios of photon numbers of two radiation fields as well as different ratios of two transitions have a remarkable influence on this distribution. It is interesting to note that under certain conditions, in this cascade structure, there is a high degree of super-Poisson distribution that has not been reported in other structures. We try to explore this anomaly in detail.

Dipole squeezing effects of a three-level cascade atom interacting with a correlated two-mode field

Tiang Yong

The dipole squeezing effects of a three level cascade atom interacting with a correlated two-mode squeezed vacuum field are investigated. After the numerical calculations, the influences of the squeezing parameters of the initial squeezed state field, the frequency detuning value of the mono photon and the intensity of atom field coupling on the atomic dipole squeezing are discussed.
