摘要
我们发现一个新κ-参数挤压了协调州的| p ， q 】
_κ 表示，它拥有行为优良特征，即，它的 Wigner 功能“ s 边缘的分发在”q方向“并且在里面”p方向“是 Gaussian 形式 exp {-κ(q''- q )~ 2 }，并且 exp {( p ”-p)~2/κ},分别地。基于这， | p 的 Husimi 功能， q 】
_ κ也被获得，它是 Gaussian 拓宽 Wigner 功能的版本。| p， q 】
_ κ状态为学习 Husimi 操作员的各种各样的性质提供一个好代表性的空格。
We find a new x-parameter squeezed coherent state （p, q）κ representation, which possesses well-behaved features, i.e., its Wigner function＇s marginal distribution in the ＂q-direction＂ and in the ＂p-direction＂ is the Gauss/an form exp（-κ（q＇ - q）2}, and exp{（p＇ - p）2/κ}, respectively. Based on this, the Husimi function of（p, q）κ is also obtained, which is a Gauss/an broaden version of the Wigner function. The （P, q）κ state provides a good representative space for studying various properties ot the Husimi operator.
