Effect of Dipole Interaction on the Vacuum Field Rabi Oscillations of Two-level Atoms in an Ideal Cavity

Abstract

We have re-examined the vacuum field Rabi oscillations of two interacting (via dipole–dipole interaction) two-level atoms in an ideal cavity. The analytic expression of the spectrum for such a system in the vacuum field is explicitly derived. We find that the symmetry of the spectrum is lost due to nonzero dipole interaction between atoms.

Emission spectrum of a pair of two-level atoms in a cavity

Lei Xu, Zhi‐Ming Zhang, Zhenfei Luo

The emission spectrum of a pair of two-level atoms interacting with a single mode of radiation field in an ideal cavity is investigated, where the interaction of each atom with the field may be different. A general expression for the emission spectrum is presented and the spectrum is studied numerically when the radiation field is initially in the vacuum state, pure number state and squeezed-vacuum state, respectively. The effects of the ratio of two coupling constants (R=g 2 /g 1 ) on the emission spectrum are discussed. In contrast with the spectrum of a one-atom system, the spectrum of a two-atom system is much more complicated. Generally, the emission spectrum shows a 12-peak structure for the vacuum state and 16-peak structure for the pure number state. For the squeezed-vacuum state, it is found that the Rabi splitting is most apparent when R=1.

Vacuum-field Rabi oscillations in a bimodal cavity

Ho Trung Dung, A.S. Shumovsky

Examining the spontaneous emission of a two-level atom interacting at the same time with two modes of the cavity radiation field the authors show that such multimode coupling may lead to irregular patterns in the vacuum-field Rabi oscillations. It also leads to the appearance of a new line in the spontaneous emission spectra in comparison with the case of single-mode single-atom coupling.

Effects of dipole-dipole interaction on the emission spectrum of atoms

Xu Li, Zhenfei Xu, Z Zhang

The emission spectrum of a pair of two-level atoms coupled by dipole-dipole force in a single-mode radiation field is Studied. It is found that atomic dipole-dipole interaction destroys the symmetry of the spectrum. The spectral properties for the vacuum field and strong field are discussed in detail.

Cooperative Effects on Rabi Oscillations in a Damped Cavity

Sajid Mahmood, Muhammad Suhail Zubairy

Exact closed equations of motion for the population inversion of two two-level atoms interacting with the vacuum field inside a damped resonant cavity are derived. Numerical results exhibiting the effect of cooperation on the dynamics of the atoms are presented. In particular, single-atom Rabi oscillations are studied under the influence of another atom for various coupling strengths.

Effects of Dipole Interaction on the Collapse-revival Phenomenon of Rabi Oscillations

Amitabh Joshi, S. V. Lawande

The sensitivity of the collapse-revival phenomenon of Rabi oscillations of two identical atoms to dipole-dipole interaction is brought out by deriving the analytical expression of the excitation probability of two interacting atoms in a coherent field. We study this effect in a two-photon model in which the time evolution is exactly periodic.

Field and atomic dipole squeezing and emission spectra with two atoms in the cavity

Tariq Maqbool, M. S. K. Razmi

We investigate effects that the presence of a second atom has on the dynamic characteristics of a field and an atom in a single-mode cavity, with particular reference to the nonclassical features of the atom–field interaction. The field statistics are marginally altered, but the field and the atomic dipole squeezing are significantly altered. The vacuum-field Rabi splitting, which produces only two peaks in the emission spectrum of an isolated atom, gives a far more complex spectrum when another atom is present in the cavity.
