V-type three-level-atom mazer with atomic coherence: velocity selection

We investigate the entanglement dynamics and coherence loss of a two-level atom dispersively interacting with two coherent fields in a dissipative cavity by using the concurrence and linear entropy, respectively. It is shown that the atomic coherence can lead to entanglement between the atom and one mode while the two modes are always separable. We also find that there is long-lived coherence loss as the system evolves.

External Driving

By using the full quantum theory, we investigate the time evolution of the atomic dipole squeezing parameters of a Λ-type three-level atom interacting with a single-mode coherent optical field, and study the influence of the initial coherent-field intensity, the initial atomic coherence, the initial populations and energy splitting of the two lower atomic levels on the atomic dipole squeezing. The influence of a classical external driving field coupling to the atom on the atomic dipole squeezing is also explored at the end of the paper.

The Pancharatnam phase for the entangled state of a single three-level atom interacting with a single electromagnetic field mode has been studied. The exact results are employed to perform a careful investigation of the influence of the second-order correction to Rayleigh scattering on the atomic level occupation probabilities as well as the Pancharatnam phase. It is shown that the Pancharatnam phase explicity contains information about the statistics of the field and atomic coherence. The addition of a second-order correction term has an important effect on the properties of the Pancharatnam phase. The results show that the effect of the second-order correction term changes the quasi-period of the Pancharatnam phase evolution.
