Entanglement of three cavity fields via resonant interactions with dressed three-level atoms
Jinhua Zou
In this paper we show that three cavity fields can be entangled when they are tuned on resonance with an ensemble of dressed three-level atoms. The master equation for the three ca…

Generation of two-mode entanglement via atomic coherence created by non-resonant dressed-state transitions
Jinhua Zou, Dahai Xu, Huafeng Zhang
Two-mode squeezing and entanglement is obtained in a atom-cavity system cosisting a three-level atom and a two-mode cavity with driving laser fields. Here non-resonatn dressed-stat…

Amplitude and phase control of gain without inversion in a four-level atomic system using loop-transitio
Jinhua Zou, Dahai Xu, Huafeng Zhang
Amplitude and phase control of gain without inversion is investigated in a four level loop-structure atomic system. Two features are presented. One is that gain without inversion c…
