| 摘 要： | 利用Zhang等人提出的单模辐射场的振幅N次方压缩理论,研究了有限维希尔伯特空间中单参数q变形非简谐振子广义相干态的振幅N次方压缩效应.结果发现:该量子光场的确存在场的振幅N次方压缩效应,其压缩条件分别与相位角Φ、维度参数s、压缩幂次N、平均光子数的方根r和变形参数q相关;这一结果与无限维希尔伯特空间单参数q变形广义相干态的情形截然不同. |

| Abstract: | The property of N-th power squeezing of field-amplitude on generalized single-parameter q-deformation coherent state of an anharmonic oscillator in a finite-dimensional Hilbert space is studied firstly and systematically. By utilizing the theory of N-th power squeezing of the field-amplitude of single-mode radiation field, which is proposed by Zhang Zhiming et al. It is found firstly that there exists really the effect of N-th power squeezing of the field-amplitude on generalized single-parameter q-deformation coherent state of an anharmonic oscillator in a finite-dimension Hilbert space, and the condition of squeezing closely relates to parameters Φ、S、r and q, which are rather different from the case of generalized single-parameter q-deformation coherent state generated by an anharmonic oscillator in the infinite-dimension Hilbert space. |
