平方可积球函数的新表示

New representations for square-integrable spheroidal functions

V. N. Kovalenko, A. M. Puchkov

摘要:

本文讨论了扁球坐标系下薛定谔方程中分离变量后的边值问题的解。这些边值问题的特殊性在于微分方程的奇异点在本征函数被考虑的区域之外。这就阻止了本征函数作为收敛级数的构造。为了解决这个问题,我们推广和应用Jaffe变换。在电荷参数为零的特殊情况下,我们找到了问题的三角级数和幂级数的解。将所得结果应用于椭球形势阱形式的量子环模型的谱问题,并引入有限深势阱进行了讨论。

英文摘要:

We discuss the solution of boundary value problems that arise after the separation of variables in the Schrödinger equation in oblate spheroidal coordinates. The specificity of these boundary value problems is that the singular points of the differential equation are outside the region in which the eigenfunctions are considered. This prevents the construction of eigenfunctions as a convergent series. To solve this problem, we generalize and apply the Jaffe transformation. We find the solution of the problem as trigonometric and power series in the particular case when the charge parameter is zero. Application of the obtained results to the spectral problem for the model of a quantum ring in the form of a potential well of a spheroidal shape is discussed with introducing a potential well of a finite depth.
