非简谐振子Klauder-Perelomov相干态的维格纳函数

Wigner Functions of the Klauder-Perelomov Coherent States for the Pseudoharmonic Oscillator

利用相干态表象下的维格纳算符和有序算符内的积分技术(IWOP技术),重构了非简谐振子Klauder-Perelomov(K-P)相干态的维格纳函数,并研究了维格纳函数随参数k和z的变化.结果表明,非简谐振子K-P相干态具有很好的量子特性.

Using the coherent state representation of Wigner operator and the tec hnique of integration within an ordered product（IWOP） of operators,the Wigner functions of the Klauder-Perelomov coherent states for the pseudoharmonic oscil lator were obtained and the variations of the Wigner functions with the parameters k and z were discussed.The results revealed well interference properties of the K lauder-Perelomov coherent states for the pseudoharmonic oscillator.
