Amplitude-squared (AS) squeezing has been investigated for the m-photon Jaynes-Cummings model assuming the field to be initially in the squeezed states. The role played by intensity-dependent coupling has also been discussed. It has been shown that f

A nondegenerate two-photon Jaynes-Cummings model is analyzed for its atomic-dipole squeezing and emission spectra. The input fields are assumed to be coherent or squeezed. The atomic dipole squeezes both for the on- and off-resonance excitations, sho

We study atomic dipole squeezing in the presence of the Stark shift for a two-photon Jaynes-Cummings model. With an initial coherent field, both the dispersive and absorptive components are found to squeeze when the Stark shift is present but only th

Third order nonlinear susceptibility of two-level atoms dressed by the cavity vacuum is studied to see the effect of Rabi oscillations. It is found that while the interference effects remove the peaks of on-resonance third harmonic generation, peak s

Atomic-dipole squeezing in the presence of the Stark shift in two-photon Jaynes-Cummings model for an atom initially prepared in a coherent superposition of states, interacting with the coherent- or squeezed-vacuum-state field, is studied. Closed exp

An analysis of the amplitude-squared squeezing is presented for the lossless anharmonic-oscillator, Jaynes-Cummings, and intensity-dependent coupling Jaynes-Cummings models using coherent and squeezed inputs. Periodic revivals of the amplitude-square

An m-photon Jaynes-Cummings model is analyzed assuming the field to be initially in the squeezed vacuum state or in a more general squeezed state. Collapses and revivals of the Rabi oscillations in the atomic population inversion appear for a general

The emission spectrum of the atom and the cavity field spectrum of the two-photon Jaynes–Cummings model are studied, with the input field assumed to be in a number state, a thermal state, a squeezed vacuum state, and a coherent state. The effects o
