一类新的精确可解系统的SWKB条件的数值研究

Numerical study of the SWKB condition of novel classes of exactly solvable systems

Yuta Nasuda, Nobuyuki Sawado

摘要:

对于所有已知的具有形状不变性的精确可解量子力学系统,超对称WKB(SWKB)条件都是精确的。近年来,有人指出,对于本征函数由例外正交多项式组成的广义径向振子,即使系统具有形状不变性,其SWKB条件也不是精确的.本文研究了两类新的精确可解系统的SWKB条件:一种是以多指标Laguerre多项式和Jacobi多项式作为特征函数的主要部分,另一种是以Krein-Adler Hermite多项式、Laguerre多项式和Jacobi多项式作为特征函数的主要部分,总是可以从条件中去除$\hbar$依赖性,并且满足一定的精确度。

英文摘要:

The supersymmetric WKB (SWKB) condition is supposed to be exact for all known exactly solvable quantum mechanical systems with the shape invariance. Recently, it was claimed that the SWKB condition was not exact for the extended radial oscillator, whose eigenfunctions consisted of the the exceptional orthogonal polynomial, even the system possesses the shapeinvariance.In this paper, we examine the SWKB condition for the two novel classes of exactly solvable systems: one has the multi-indexed Laguerre and Jacobi polynomials as the main parts of the eigenfunctions, and the other has the Krein--Adler Hermite, Laguerre and Jacobipolynomials.For all of them, one can always remove the $\hbar$-dependency from the condition, and it is satisfied with a certain degree of accuracy.
