The q-coherent states(q-CSs) of the q-deformed harmonic oscillator(q-HO) in a finite-dimensional Hilbert space(FDHS)are introduced. It is shown that the q-CSs have some nontrivial properties and some other CSs may be considered as special cases of the q-CSs. The dynamical behaviours of the q-HO initially prepared in the q-CSs are studied. The time evolution of the q-squeezing of the q-CSs for the quadrature operators are analyzed for some simple cases.

本文研究了有限维希尔伯特空间中q-变形谐振子的q-相干态,结果表明,q-相干态有一些非平庸的特性,而其他的相干态可作为q-相干态的特殊情形考虑,q-谐振子的动力学特性最初在q-相干态得以讨论,对于一些简单的情形分析了正交算符q-相干态的q-压缩的时间演化。

In this paper, we investigate the higher order squeezing properties of even and odd coherent states of a harmonic oscillator in a finite dimensional Fock space. In particular, the arbitrary higher order squeezing of the quadrature operators in these states is studied. It is shown that in definite conditions, the quadrature operators in even coherent states have 2Nth order squeezing , and the different order squeezing exhibit their maximum squeezing under the same conditions.
