Abstract

Jaynes-Cummings model (JCM) for describing a two-level atom interacting with a single-mode radiation field via the one-photon transition is one of the important theoretical models in quantum optics. Recently, Sukumar et al. have generalized the JCM to

A Possible Generalization of Jaynes–Cummings Model with Degenerate Spectrum

Wu Qiang, Fan Hong-Yi

We propose a generalized Jaynes–Cummings model (JCM) for three two-level atoms and three-mode radiation field with the interaction being . This model is characteristic of possessing partly degenerate spectrum. Some transition process of this system is calculated.

THE QUANTUM STATISTICAL PROPERTIES OF THE JAYNES-CUMMINGS MODEL

GU QIAO, 西北大学物理系

We derive a set of equations characterizing the quantum statistical properties of Jaynes-Cummings model, which may be used to describe overall the dynamical and statistical aspects in the interaction between a two-level atom and a single mode of the radiation field. Both interactions of a two-level atom with a vacuum field and a excited atom with a coherent field, as examples, are discussed in detail. Finally, the practicality of the above-mentionedi theoretical studies is demonstrated.

One-atom maser theory: photon losses and spectra

Alexander V. Gorokhov, Ilya E. Sinaiski

The Jaynes-Cummings model (JCM) of two-level atom interacting with the photon mode in ideal cavity plays an essential role in modern quantum optics. In previous papers an exact form of density matrix of the JCM with photons dissipation was found. In this article it is considered a partial case of cavity with zero temperature and obtained an exact expression for photon spectra and spectra of the mean number of photons in a cavity.

Generalized Jaynes-Cummings models with a time-dependent atom-field coupling

Amitabh Joshi, S. V. Lawande

An extension of the standard one-photon as well as the two-photon Jaynes-Cummings (JC) model has been done to include transient effects due to a modulation of the atom-field coupling coefficient. An explicit time dependence is given for the case of a linear sweep of the coupling parameter. We have shown the effects of such a sweep on the dynamical evolution of a two-level atom undergoing a one- or two-photon process in a single nondecaying mode of the field in a coherent state. The statistical aspects of the field, such as intensity-intensity correlation and squeezing, are also investigated and are found to be both qualitatively as well as quantitatively different from the standard JC models.

The f-deformed Jaynes–Cummings model and its nonlinear coherent states

O de los Santos-Sánchez, J. Récamier

Based on the f-oscillator formalism, we introduce a nonlinear Jaynes–Cummings model (NJCM) which is constructed from the standard JCM by deforming the single-mode field operators. Such a generalization of the JCM describes the interaction of a two-level atom with a single mode of the electromagnetic field in the presence of a nonlinear Kerr-like medium. Since the medium is modelled as an f-oscillator, it is possible to consider the field f-coherent states (nonlinear coherent states) and their evolution.
