高维非谐振子的精确可解性

On Exact Solvability of Anharmonic Oscillators in Large Dimensions

Vladimir Gerdt, Denis Yanovich, Miloslav Znojil

摘要:

考虑了中心多项式势依赖于$2q$任意耦合常数的广义薛定谔方程。其所谓的Magyari类型的例外解决方案(即,与次数$N$的多项式成比例的精确束缚态)。在任何空间维度$D \geq 1$,这个问题导致Magyari的系统耦合多项式约束,只有纯数值解似乎可在一个通用的选择$q$和$N$。然而,我们解决了该系统的建设珍妮特基地在度逆字典序,其次是他们的转换成纯字典序Gröbner基地。对于非常大的$D$,我们发现:(a)确定“可接受”(这意味着,真正的)能量变得非常方便,在这种语言;(b)由此产生的单变量“世俗”多项式证明因式分解,完全出乎意料的,在一个完全非数值的方式。这意味着由于Janet基的使用,我们在量子力学中发现了一类新的精确可解模型。

英文摘要:

General Schrödinger equation is considered with a central polynomial potential depending on $2q$ arbitrary coupling constants. Its exceptional solutions of the so called Magyari type (i.e., exact bound states proportional to a polynomial of degree $N$) are sought. In any spatial dimension $D \geq 1$, this problem leads to the Magyari's system of coupled polynomial constraints, and only purely numerical solutions seem available at a generic choice of $q$ and $N$. Routinely, we solved the system by the construction of the Janet bases in a degree-reverse-lexicographical ordering, followed by their conversion into the pure lexicographical Gröbner bases. For very large $D$ we discovered that (a) the determination of the "acceptable" (which means, real) energies becomes extremely facilitated in this language; (b) the resulting univariate "secular" polynomial proved to factorize, utterly unexpectedly, in a fully non-numerical manner. This means that due to the use of the Janet bases we found a new exactly solvable class of models in quantum mechanics.
