Physical Review A

Abstract

We analyze the phase properties of a strong cavity field interacting with an ensemble of initially excited N two-level atoms. Using the Pegg-Barnett phase formalism [Phys. Rev. A 39, 1665 (1989)], we calculate the phase probability distribution as well as the phase variance. The phase probability density exhibits a (N+1)-peak structure at the initial stages of the evolution. The phase variance is used to illustrate the progressive randomization of the phase on the long-time evolution. The difference in the phase dynamics for the N even and the N odd case is pointed out.

Phase Properties of a Strong Field Interacting with Many Atoms with and Without Initial Atomic Coherences

Xiang Ming Hu

The phase distributions of an initially strong, coherent, single-mode field interacting with one, two, three and four identical atoms with and without initial atomic coherences using the Pegg-Barnett Hermitian phase operator formalism have been examined. A number of interesting features of the phase distributions are revealed. A link between the coincidences of the peaks in the phase probability distribution and the revivals in the two-atom case is also shown.

Phase of the field in the interaction with two two-level atoms

Igor Jex, Masaya Matsuoka, Masato Koashi

The authors present phase properties of a field mode interacting with two two-level atoms using the Pegg and Barnett formalism. They derive analytical and approximate expressions for the phase probability distribution, and calculate the mean value of the phase and their fluctuations. A discussion with respect to the coupling constant of the atoms is given.

Phase properties of the field interacting with a three-level atom. I. One-mode case

E.I. Aliskenderov, Ho Trung Dung, A.S. Shumovsky

Phase properties of a one-mode coherent field interacting with a three-level atom under two-photon resonance are studied using the new phase formalism of Pegg and Barnett (1988). The connection between the collapse and revival phenomenon and dynamical properties of the field phase is found. Interesting features such as the partial trapping of the field phase in its initial state are discovered and discussed.

Dynamical Properties of the Field Phase in the Jaynes-Cummings Model

Ho Trung Dung, R. Tanaś, A.S. Shumovsky

Phase properties of a coherent field interacting with a two-level atom in an ideal cavity are studied using the new hermitian phase formalism of Pegg and Barnett. It is shown in particular that phase properties of the field reflect the collapse and revival phenomena. The effects of finite detuning and atomic coherences are treated. The results for the variance of the phase cosine are obtained and compared with those based on earlier approaches.

Phase properties of a field interacting with a three-level atom with a Kerr-like medium are investigated through the phase formalism of Pegg and Barnett. The phase probability distribution, the expectation value and the phase fluctuations of the Hermitian phase operator are calculated. The phase properties of the field reflect the collapses and revivals. A number of interesting features are found and discussed.
