偶奇qs相干态的非经典特性

利用数值计算方法研究了ｑ和ｓ畸变对双参数形变偶奇ｑｓ相干态量子统计特性的委现偶奇ｑｓ相干态与通常的偶奇相干态有着显著不同的量子统计性质，压缩效应和反聚束效应均可在一定条件下的两种双参数畸变态中出现，偶奇ｑｓ相干态和通常偶奇相干态的差异随ｑ值偏离１越大和ｓ的取值越小而越大。

Nonclassical Properties of Even and Odd qs-Coherent States

The numerical method is used to study the influences of q and s deformation on the quantum statistical properties of even and odd qs-coherent states. It is shown that noncalssical properties of even and odd qs-coherent states are very different from those of the usual even and odd coherent states. It is found that squeezing and antibunching effect appear for both even and odd qs-coherent states in some range of the parameters q, s and r. The smaller the q(q<1) and s, the larger the difference between even and odd qs-coherent states and the usual even and odd coherent states.
