Abstract

The significance of the counterrotating terms in the many-atom Jaynes–Cummings model with cavity damping is demonstrated. Numerical results for the time evolution of the atomic population inversion for various numbers of atoms and different cavity dampings in the case of spontaneous emission are presented. The appearance of new steady states under the influence of the counterrotating terms is pointed out.

The Effect of the Counter-Rotating Terms on the Rabi Oscillations and Steady States in the Few-Atom Jaynes-Cummings Model with Cavity Losses

JOSIP SEKE, Gerhard Adam, Otto Hittmaır

durch das w. M. Otto Hittmair) The effect of the counter-rotating terms in the few-atom Jaynes-Cummings model is examined in both lossless cavities and cavities with losses. Numerical results for the time evolutions of the atomic populations inversion and dipole moment for an initial coherent field are presented for various numbers of atoms. As a consequence of the counter-rotating terms, the appearance of new steady states for atomic population inversion in the case of cavities with losses is pointed out.

INFLUENCE OF THE COUNTER-ROTATING TERMS ON THE RABI OSCILLATIONS IN THE POLYATOMIC JAYNES-CUMMINGS MODEL WITH CAVITY LOSSES FOR INITIAL FOCK-STATE FIELDS

JOSIP SEKE

The significance of the counter-rotating terms in the polyatomic Jaynes-Cummings model with cavity losses is demonstrated. Numerical results for the time evolution of the atomic population inversion and dipole moment for an initial Fock-state field with different photon numbers are presented for various cavity dampings. The appearance of new steady states for the population inversion and the mean-photon number under the influence of the counter-rotating terms is pointed out. Namely, as is shown, the presence of “virtual photons”, produced by the counter-rotating terms, leads to these effects.

Many-atom Jaynes-Cummings model without rotating-wave approximation

JOSIP SEKE

The contribution of the counter-rotating terms in the many-atom Jaynes-Cummings model is examined. Numerical results for the time evolution and time averages of the atomic population inversion for various numbers of atoms and different initial fields (Fock and coherent-state fields) are presented. The results demonstrate the significance of the counter-rotating terms.

INFLUENCE OF THE COUNTER-ROTATING TERMS ON THE RABI OSCILLATIONS AND SQUEEZING IN THE JAYNES-CUMMINGS MODEL WITH CAVITY LOSSES FOR INITIAL COHERENT FIELDS

JOSIP SEKE

The significance of the counter-rotating terms in the Jaynes-Cummings model with cavity losses is demonstrated. Numerical results for the time evolution of the atomic population inversion, dipole moment, and atomic and field squeezing parameters for an initial coherent field are presented for different cavity dampings. In low-Q cavities the counter-rotating terms lead to the appearance of new steady states.

The effect of the counter-rotating terms in the case of the Jaynes-Cummings model with cavity losses: novel dynamical and steady-state behaviour

JOSIP SEKE

It is pointed out that the inclusion of the counter-rotating terms into the Jaynes-Cummings model with cavity losses changes the dynamical and steady-state behaviour of the decaying system to the extent that a prevention of the total atomic deexcitation, leading to novel steady states, occurs. Numerical and analytic results demonstrate the significance of the counter-rotating terms in both high- and low-Q cavities.
