| 摘 要： | 利用SU(2)李代数讨论了原子相干态中角动量的二阶、四阶和六阶涨落,并在高阶不确定关系基础上提出了角动量高阶压缩的定义.研究了原子相干态中角动量涨落的二阶、四阶和六阶压缩情况.运用这里的定义和方法可进一步研究更高阶的压缩情况,从而把高阶压缩推广到原子算符的涨落上.

| Abstract: | The second ,fourth and sixth order fluctuations have been discussed by making use of SU (2)Lie algebra.On the basis of higher order uncertainty relation,the definition of higher order squeezing for the fluctuations of angular momentum has been put forward.In particular,the second ,fourth and sixth order squeezing in atomic coherent states are investigated.These methods and definition can be used for studying much higher order squeezing.The higher order squeezing can be generalized to the fluctuations of atomic variances thereby. |
