含有三参数的广义压缩态及其特性
New generalized squeezed states with three parameters and their nonclassical behaviors
摘要
Abstract
As an extension of ordinary squeezed states,a class of generalized squeezed states with three parameters is theoretically proposed by acting a complex evolution operator on vacuum,and their nonclas-sical properties are explored based on the sub-Poisson distribution,photon number distribution,entangle-ment entropy,and Wigner distribution function.The results show that,compared to ordinary squeezed states,the new generalized squeezed states exhibit more significant sub-Poisson distribution,entangle-ment,and squeezing characteristics when the three parameters take certain specific values.关键词
