Abstract

The evolution properties of the phase of the two mode field for non degenerate Raman process are studied by means of the Pegg Barnett phase theory.The influece of the atomic coherence and the AC Stark shift on the phase probability distribution,the phase diffusion and the frequency shift are discussed.

Influence of AC-Stark Shift on Fidelity in Non-Degenerate Raman Process

Bao Xiu-li

With modified effective Hamiltonian for non-degenerate Raman process,we have calculated the evolution of the fidelity of the system,the field and the atom,and investigated the influence of the ACStark shift on the evolution of the fidelity of the system,the field,the atom and the atom-field entanglement.It shows that in the presence of AC-Stark shift,the evolution period of the system,the field and the atom diminish,and the degree of atom-field entanglement is affected by the AC-Stark shift.

Phase Properties of Two-Mode Optical Fields with Stark Shift and Kerr Nonlinearity

A.‐S. F. Obada, A.M. Abdel-Hafez, Mahmoud Abdel‐Aty

The influence of Stark shift on the phase properties when an ideal cavity is filled with a Kerr-like medium and coupling is effected through nondegenerate Raman two-photon processes is studied. This has been carried out using the Hermitian phase formalism of Pegg and Barnett. We find that the phase properties of the field reflect the collapses and revivals of the level occupation probabilities in most situations. The interaction brings about the symmetrical splitting of the phase probability distribution. A number of interesting features are found and discussed.

Phase properties of the radiation fields in Raman process

Peng Zhou

The general evolution of the interaction of two radiation fields with an effective two-level atom via the Raman-type transitions is presented. Using the Pegg-Barnett phase theory, the joint phase probability distribution of the two field modes, phase average values and phase fluctuations are studied in detail. Also, the effect of the presence of a field on the phase properties of the other mode is examined.

Influence of the dipole-dipole interaction between atoms on the phase properties of light

Tian Yong-hong, PENG JIN-SHENG, Dahai Xu +1 more

The time evolution and the statistic characteristic of the light phase in the Tavis-Cummings (T-C) model of two identical two-level atoms coupled to a strong coherent light field are studied by means of the Pegg-Barnett phase theory. It is proved that the dipole-dipole interaction between atoms will lead to the frequency shift of light, the weakening of the degree of atom-field coupling and the restraint of light phase diffusion.

Influences of ac Stark shifts on coherent population trapping in the atom-field coupling system via Raman two-photon processes

Gao‐xiang Li, Jin-sheng Peng

By means of adiabatically eliminating the upper level or levels of a \ensuremath{\Lambda}-configuration atom coupling to a two-mode quantized field, we have studied the influences of ac Stark shifts on the atomic coherent population trapping in two important atom-field coupling systems via nondegenerate Raman two-photon processes. The states of the field that trap the atom in its two nondegenerate lower levels are obtained, and the important roles of ac Stark shifts and properties of the atomic upper level or levels in the states of the trapping field in two Raman-coupling systems are also analyzed.
