增光子压缩真空态的反群聚效应

Anti-bunching Effects of the Photon-added Squeezed Vacuum States

本文讨论了压缩真空态在玻色湮灭算符的逆算符及玻色产生算符作用下的光子反群聚性质.结果表明,在两种情况下所得到的增光子压缩真空态都呈现出反群聚效应,但前者呈现的反群聚效应与所增加的光子数k以及压缩参数的取值区间有关,而后者则在相同的压缩参数取值区间内呈现出反群聚效应,与增加的光子数k无关.

The anti-bunching properties of photons in the photon-added squeezed vacuum states were discussed in this paper. The results show that both Boson inverse operators and Boson operators acting on the usual squeezed vacuum states appear the anti-bunching effects. However,the effects due to the actions of Boson inverse operators are related to the squeeze parameter of the squeezed vacuum states and the number k of the added photons. Those due to the actions of Boson operators have the same squeeze parameter range but have no relatonship with the number k of the added photons.
