一维薛定谔问题的谱zeta函数

Spectral zeta functions of a 1D Schrödinger problem

Joe Watkins

摘要:

本文研究了势为V(x)=x^{2 M}+alpha x^{M-1}+(α 2 -1/4)/x ^2的径向薛定谔问题的谱zeta函数。使用量子朗斯基方程,我们提供的结果,如封闭形式的评价,一些第二zeta函数,即总和的逆特征值平方。并以一个特殊的5F_4超几何级数为例,讨论了如何利用所得结果导出涉及特殊函数的关系和恒等式。我们的工作,然后扩展到一类相关的PT对称特征值问题。利用融合量子朗斯基,我们给出了一个简单的方法来计算相关的光谱zeta函数。这种方法有许多应用,包括利用ODE/IM对应计算出现在相关可积量子场论中的(真空)非定域运动积分G_n。

英文摘要:

We study the spectral zeta functions associated to the radial Schrödinger problem with potential V(x)=x^{2M}+alpha x^{M-1}+(lambda^2-1/4)/x^2. Using the quantum Wronskian equation, we provide results such as closed-form evaluations for some of the second zeta functions i.e. the sum over the inverse eigenvalues squared. Also we discuss how our results can be used to derive relationships and identities involving special functions, using a particular 5F_4 hypergeometric series as an example. Our work is then extended to a class of related PT-symmetric eigenvalue problems. Using the fused quantum Wronskian we give a simple method for calculating the related spectral zeta functions. This method has a number of applications including the use of the ODE/IM correspondence to compute the (vacuum) nonlocal integrals of motion G_n which appear in an associated integrable quantum field theory.
