Abstract

Abstract We construct a new class of nonlinear coherent states for the isotonic oscillator by replacing the factorial of the coefficients z n / n ! ${z}^{n}/\sqrt{n!}$ of the canonical coherent states by the factorial x n γ ! = x 1 γ . x 2 γ x n γ ${x}_{n}^{\gamma }!={x}_{1}^{\gamma }.{x}_{2}^{\gamma }\dots {x}_{n}^{\gamma }$ with x 0 γ = 0 ${x}_{0}^{\gamma }=0$ , where x n γ ${x}_{n}^{\gamma }$ is a sequence of positive numbers and γ is a positive real parameter. This also leads to the construction of a Bargmann-type integral transform which will allow us to find some integral transforms for orthogonal polynomials. The statistics of our coherent states will also be considered by the calculus of one called Mandel parameter. The squeezing phenomenon was also discussed.

等振子非线性相干态的巴格曼变换和统计性质
通过替换系数z n / n的阶乘,构造了一类新的等压振荡器的非线性相干态。${z}^{n}/\sqrt{n!}$正则相干态的阶乘x n γ != x1 γ。x2 γ…X n γ ${x}_{n}^{\gamma }!={x}_{1}^{\gamma }.{x}_{2}^{\gamma }\dots {x}_{n}^{\gamma }$其中X 0 γ = 0 ${x}_{0}^{\gamma }=0$,其中X n γ ${x}_{n}^{\gamma }$是一个正数序列,γ是一个正实参数。这也导致了巴格曼型积分变换的构造,它将使我们能够找到正交多项式的一些积分变换。相干态的统计也将通过曼德尔参数的演算来考虑。并对挤压现象进行了讨论。

期刊介绍: A Journal of Physical Sciences: Zeitschrift für Naturforschung A (ZNA) is an international scientific journal which publishes original research papers from all areas of experimental and theoretical physics. Authors are encouraged to pay particular attention to a clear exposition of their respective subject, addressing a wide readership. In accordance with the name of our journal, which means “Journal for Natural Sciences”, manuscripts submitted to ZNA should have a tangible connection to actual physical phenomena. In particular, we welcome experiment-oriented contributions.
