| 摘 要： | 利用广义Weyl对应导出了相干态密度算符的S-编序表示.通过此表示并结合S-编序内的算符积分技术,导出了若干量子玻色算符的S-编序形式(包含了正规编序、Weyl编序和反正规编序).此方法进一步推广了相干态在算符编序中的应用.

| Abstract: | The S-ordering expansion of density operator of coherent state is obtained by means of the generalized Weyl quantization scheme.Based on this S-ordered expression and the technique of integration within S-ordered product of operators,we derive the S-ordering forms of some quantum operators(including normally ordered,Weyl ordered and antinormally ordered product of operators).The proposed method further expands the application of the coherent state on the ordering of quantum operators. |
