一类新的拟精确可解差分方程

New Quasi Exactly Solvable Difference Equation

Ryu Sasaki

摘要:

在Schroedinger和Heisenberg图像水平上证明了离散量子力学的两个典型例子--Meixner-Pollaczek动力学和全参数连续Hahn多项式动力学的精确可解性.将这两种动力学交叉,构造了一个新的拟精确可解差分方程,即连续Hahn多项式的二次势函数乘以Meixner-Pollaczek型的常数相位因子.它的普通量子力学对应物,如果存在的话,似乎并不为人所知。

英文摘要:

Exact solvability of two typical examples of the discrete quantum mechanics, i.e. the dynamics of the Meixner-Pollaczek and the continuous Hahn polynomials with full parameters, is newly demonstrated both at the Schroedinger and Heisenberg picture levels. A new quasi exactly solvable difference equation is constructed by crossing these two dynamics, that is, the quadratic potential function of the continuous Hahn polynomial is multiplied by the constant phase factor of the Meixner-Pollaczek type. Its ordinary quantum mechanical counterpart, if exists, does not seem to be known.
