摘要
构造了有限维空间非谐振子广义偶奇相干态 ,并运用数值计算方法研究了其非经典特性。结果表明 ,相对于无限维情景 ,随空间维数减小 ,广义偶奇相干态的压缩反常现象均削弱 ,广义偶相干态的反聚束反常现象增强 ;而广义奇相干态出现反聚束反常现象的区间缩小但反聚束程度加强。
The generalized even and odd coheren t states (E-O CSs) of a finite-dimensional space non-harmonic oscillator are c onstructed,and their nonclassical properties are studied by numerical method.It is found that,compare to a infinite-dimensional space,with the dimensions numbe r reducing,the unusual squeezing phenomenon is seaken in both generalized E-O C Ss,the unusual antibunching phenomenon in generalized ECSs is enhanced.And the range of appearing unusual antibunching phenomenon is reduced but the degree of antibunching effect is enhanced in generalized OCSs.
