摘要
研究q-玻色湮没算符高次幂(k≥3)的正交归一本征态的数学结构,在此基础上讨论了它们的数学性质及其q-压缩和振幅N次方压缩特性.发现它们能组成一个完备的希尔伯特(Hilbert)空间;且当k为偶数时,这些本征态均可存在振幅N次方压缩.
In this paper, the mathematical structure of k orthonormalized eigenstutds of the higher powers (k≥3) of the q-boson annihilation operator are studied. Based on the work, the properties of the mathematics, q-squeezing and the amplitude N th-power squeezing are investigated. It is found that they form a complete q-Hilbert sauce, and the amplitude N th-power squeezing [N = (m + 1 /2)k, m = 0, 1, 2, ...] can exist in the all of them when k is even.
