对称Poschl-Teller振子相干态的正交多项式

Orthogonal polynomials attached to coherent states for the symmetric Poschl-Teller oscillator

Khalid Ahbli, Patrick Kayupe Kikodio, Zouhair Mouayn

摘要:

我们考虑了一个单参数族的非线性相干态,用一个依赖于参数γ的特定广义阶乘来代替正则相干态系数中的阶乘。这些状态是具有对称Poschl-Teller势的哈密顿量的本征态的叠加,取决于参数nu > 1。相关的Bargmann类型变换是为相等参数定义的。本文还导出了关于无限深方势阱的一些结果。对于一些不同的伽玛值,我们讨论了两组正交多项式,自然地附着到这些相干态。

英文摘要:

We consider a one-parameter family of nonlinear coherent states by replacing the factorial in coefficients of the canonical coherent states by a specific generalized factorial depending on a parameter gamma. These states are superposition of eigenstates of the Hamiltonian with a symmetric Poschl-Teller potential depending on a parameter nu > 1. The associated Bargmann-type transform is defined for equal parameters. Some results on the infinite square well potential are also derived. For some different values of gamma, we discuss two sets of orthogonal polynomials that are naturally attached to these coherent states.
