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 influence of the counter-rotating terms in the polyatomic Jaynes-Cummings model with cavity losses is investigated. Numerical results for the time evolution of the atomic population inversion, dipole moment, mean-photon number and atomic and field squeezing parameters for an initial coherent field are presented for different cavity dampings. As a consequence of the counter-rotating terms, the appearance of new steady states for the population inversion and the mean-photon number is pointed out.

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.

We investigate the dynamics of the Jaynes-Cummings model with the cavity field initially prepared in the displaced number state. The time evolution of the atomic population inversion, squeezing of the cavity field and the emission spectra from the two-level atom are studied.

Spherical Bubble

We consider a finite-size spherical bubble with a nonequilibrium value of the q-field, where the bubble is immersed in an infinite vacuum with the constant equilibrium value q 0 for the q-field (this q 0 has already cancelled an initial cosmological constant). Numerical results are presented for the time evolution of such a q-bubble with gravity turned off and with gravity turned on. For small enough bubbles and a q-field energy scale sufficiently below the gravitational energy scale E Planck , the vacuum energy of the q-bubble is found to disperse completely. For large enough bubbles and a finite value of E Planck , the vacuum energy of the q-bubble disperses only partially and there occurs gravitational collapse near the bubble center.
