摘　　要：构造了q形变的非谐振子广义偶奇相干态 ,并研究了其高阶压缩和高阶反聚束特性 .结果表明 ,广义偶奇q-相干态都在不同的参数区存在压缩效应 ,随q变形的增大 ,偶q -相干态的高阶压缩效应减弱而奇q-相干态的高阶压缩效应增强 .在一定参数范围内 ,广义偶q -相干态出现高阶 (N ≥ 2 )反聚束特性而广义奇q -相干态则出现聚束效应 .随q形变增大 ,广义 (偶 )q-相干态的高阶反聚束 (聚束 )效应都增强 .The generalized even and odd coherent states of a q-Deformation Non-harmonic Oscillator(E-O q-NHCSs) are constructed,their Higher-Order Squeezing and Antibunching Properties are studied in detail.It is increasing the Squeezing effect in different parameter ranges.With q-deformation increasing,the squeezing effect of E q-NHCSs are weakened and those of O q-NHCSs are enhanced.The E q-NHCSs appear high-order(N≥2) antibunching properties while the O q-NHCSs appear high-order bunching properties in some ranges of the parameter q and r 2 with the q-deformation increasing.Both antibunching effects of E q-NHCSs and bunching effects of O q-NHCSs are enhanced.
