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.
