Abstract

The Raman interaction of a pair of two-level atoms with the radiation field is studied. The emission spectra for two interacting processes are calculated in which either two atoms couple to the field with different constants or with the same constant but at the same time the dipole-dipole interaction between two atoms being included in the consideration. The effect of the relative value of two atom-field coupling constants and also that of atomic dipole-dipo-le interaction on the emission spectra are analyzed.

Effects of Dipole Interaction on Emission Spectra of Atoms in Two-Photon Processes

Zhenfei Luo, Zhizhan Xu, Lei Xu

We study the interaction of a pair of coupling two-level atoms with a single mode of the radiation field in an ideal cavity via two-photon resonant transition and/or degenerate Raman coupled processes. In particular, we consider the emission spectra for both two-photon processes. The effects of atomic coupling are analyzed and the properties of emission spectra for large photon number of the cavity-mode are discussed.

Emission spectrum of two atoms interacting with two modes of the cavity field with different coupling constants through a multiphoton Raman process

Jian Feng, Song Tong-Qiang, Gao Yun-feng

The emission spectrum of a pair of effective two-level atoms interacting with two modes of the radiation field with different coupling constants through a multiphoton Raman process is studied. A general expression for the emission spectrum with two modes of the field being in arbitrary states is presented. Our results show that when two modes of the field are in arbitrary number states, the spectrum is always symmetric about the resonant frequency , although the Hamiltonian of the system is asymmetric which is induced by the two different atom-field coupling constants. This property is analysed with an analytic method.

Two-atom emission spectrum including dispersion force

Zhenfei Luo, Zhizhan Xu, Lei Xu +1 more

The interaction of a pair of coupling two-level atoms with a radiation field is studied. The effects of a dispersion force (dipole-dipole interaction) on the emission spectrum are analysed. It is found that the dipole-dipole interaction induces an asymmetry of the emission spectrum, which is most obvious in a vacuum field.

DYNAMICAL PROPERTIES OF THE ATOMS AND THE FIELD IN THE RAMAN INTERACTION OF TWO ATOMS WITH A SINGLE-MODE CAVITY FIELD

Tinglu Song, Jie Feng, W Wang

By analytical method, we study the effect of the relative value of two atom-field coupling constants and also that of the initial atomic states on the dynamical properties of the atoms and the field in the Raman interaction of two two-level atoms with a single-mode radiation field. The results show that there are four col-lapserevival series in the atomic Rabi oscillation and four peaks in the phase probability distribution in general.

EMISSION SPECTRA OF TWO ATOMS INTERACTING WITH TWO MODES OF THE CAVITY FIELD THROUGH RAMAN PROCESS (g1≠g2)

Feng Jian, Song Tong-Qiang, Wenzheng Wang +2 more

Emission spectra of a pair of effective two-level atoms interacting with two modes of the cavity field through Raman interaction are studied, where the interaction of each atom with the field may be different. The spectra with two modes of the cavity field being initially in various number states are analysed in detail. It is found that emission spectra manifest following new properties: When mode 1 of the cavity field is in vacuum state and the other is in the weak field , the spectrum shows symmetric ten peaks and six peaks alternately, with the increase of R=g2/g1, which reflects the different Raman interacting intensities of two atoms with the cavity field more sensitively compared with the spectrum of two atoms in a single-mode cavity. The spectrum with 01=1, n2=50 and n1 = 50, n2=1 reflects the different positions of mode 1 and mode 2 of cavity field interacting with two atoms through Raman process. Finally, the symmetric 16-peaks structure of the spectrum is explained.

Multiphoton emission spectrum of two atoms interacting with two modes of radiation field

Jian Feng, Song Tong-Qiang, Wenzheng Wang +1 more

The multiphoton emission spectrum of a pair of coupling two-level atoms interacting with two modes of the radiation field is studied. A general expression for the two-mode multiphoton emission spectrum is presented. The non-degenerate two-photon emission spectra of two atoms are calculated when the two modes of the field are in various number states and some new results are obtained. It is found that the two-atom emission spectrum in the two-mode vacuum field reflects the atomic dipole-dipole interaction more sensitively than in the case of a single-mode vacuum field.
