摘要/Abstract

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.

关键词： 广义偶奇q-相干态, 高阶压缩, 高阶反聚束

Abstract: The generalized even and odd coherent states of a q-Deformation Non-harmonic Oscillator(E-O q- NHCSs) a reconstructed, their Higher-Order Squeezing and Antibunching Prope rties are studied in detai l. It is increasing the Squeezing effect in different parameter ranges.With q- deformation increasing, the squeezing effect of E q-NHCSs a re weakened and those of O q- NHCSs are enhanced.The E q- NHCSs appear high- order(N≥2) a ntibunching properties while the Oq- NHCSs appear high- order bunching properties in some ranges of the parameter q and r² with the q- deformation in -creasing. Both antibunching effects of E q- N HCSs and bunching effects of O q- NHCSs are enhanced.

Key words: generalized even and odd q- coherent states, higher- order squeezing, higher-order antibunching
