Nonclassical properties in the resonant interaction of a three level wedge-type atom with two-mode field in coherent state
Wu Huai-Zhi, Su Wan-Jun · Chinese Physics · 2006
In this paper, we study the nonclassical properties of the electromagnetic field resulting from the interaction of a three-level ∧-type atom with a two-mode field initially in the coherent state, such as squeezing properties and sub-Poisson statistics. We show that the squeezing can be enhanced by selective atomic measurement.
