| 摘 要： | 运用数值计算方法研究了ｑ－畸变对有限维Ｈｉｌｂｅｒｔ空间谐振子偶相干态非经典特性的影响．研究表明，随ｑ－畸变增大，偶ｑ－相干态压缩效应减弱，而反聚束效应加强．但其压缩特性在Ｓ＝１的三维空间下与ｑ－畸变无关；而反聚束效应则在ｓ较小的有限维空间无畸变偶相干态下也可出现．

| Abstract: | The influences of q deformation on the quantum statistical properties ofeven q-coherent states in a finite-dimensional Hilbert spaces (FDHS) case are studiedby numerical method. It is found that, with q deformation increasing (q <1), thesqueezing degree is strengthened and the antibunching effect is weakened. Thesqueezing degrees of the q-coherent states have nothing to do with q in the 3D(s =1) Hilbert space. The antibunching effect of the even coherent states (q =1)also exists in a FDHS that s is not very large. |
