Abstract

Squeezing of the atomic dipole moment in the one-photon and two-photon Jaynes-Cummings model is investigated with different initial conditions. Almost perfect squeezing is found in certain cases.Received 13 April 1989DOI:https://doi.org/10.1103/PhysRevA.40.2504©1989 American Physical Society

Enhancement of Squeezing in Two-Photon Jaynes–Cummings Model with Atomic Measurement

Sai-Yun Ye

We investigate the squeezing properties of the cavity field in the degenerate two-photon Jaynes–Cummings model. Compared with the one-photon Jaynes–Cummings model, the squeezing is more pronounced in the case of two-photon Jaynes–Cummings model under certain conditions.

Dipole squeezing in the two-photon Jaynes-Cummings model with superposition state preparation

Peng Zhou, Jin Sheng Peng

Quantum fluctuations of atomic dipole variables in the two-photon Jaynes-Cummings model are discussed. It is shown that dipole squeezing can be exhibited in certain periods of time evolution of the system for superposition state preparations, and also that the dipole fluctuations cannot be squeezed in atomic spontaneous radiation processes.

Numerical study of squeezing in the Jaynes-Cummings model with and without the rotating wave approximation

Rui‐Hua Xie, Tie-Jun Zhout, Qin Rao

Dipole squeezing in the Jaynes-Cummings model with and without the rotating wave approximation (RWA) has been numerically studied when restricted to the following initial conditions: the field in the superposition of the vacuum and one-photon state, and the atom in the ground state. Numerical results show that even if under the condition for which the RWA is considered to be valid, there is a significant effect caused by the virtual-photon field on the dipole squeezing; in the cases of sufficiently strong coupling of the atom-field interaction, the interference between the virtual-photon processes and the real-photon processes quenches the dipole squeezing.

Effective Dipole Squeezing in the Non-degenerate Two-photon Jaynes-Cummings Model with Superposition State Preparation

M. M. Ashraf, M. S. K. Razmi

Effective dipole squeezing in the non-degenerate two-photon Jaynes-Cummings model for atom and fields initially prepared in superposition of states is investigated. It is shown that the squeezing can be exhibited in certain periods of time but it cannot be achieved for atomic spontaneous radiation processes.
