考虑具有强度耦合的广义Jaynes-Cummings模型与压缩真空相互作用.根据Pegg和Barnett新的相位理论,不仅得到了压缩真空场的相位分布,相位期待值和相位涨落的普遍表示式,及其演化图示,而且还导出了弱压缩真空和强压缩真空情形的近似角析表示式.对于压缩真空的压缩量与相位特性之间的关系进行了简要讨论.

We consider the generalized Jaynes-Cummings model with intensity - dependent coupling interacting with a squeezed vacuum. From the point of view of the new phase formalism of Pegg and Barnett, we have not only found the exact general expressions of the phase distribution and the associated expectation value and variance of the phase of the squeezed vacuum field and their evolution illustrated graphically, but also derived approximately analytic formulas of that for the weakly and strongly squeezed vacuum. The relation between squeezing and the phase properties of the squeezed vacuum is discussed briefly.
