广义MICZ-Kepler问题与酉最高权模

Generalized MICZ-Kepler Problems and Unitary Highest Weight Modules

Guowu Meng, Ruibin Zhang

摘要:

对于每一个整数$n\ge 1$,我们证明了一个$(2n+1)$维广义MICZ-开普勒问题有一个$\mr{Spin}(2, 2n+2)$动力学对称性扩展的明显$\mr{Spin}(2n+1)$对称性。束缚态的Hilbert空间被示出形成酉最高权$\mr{Spin}(2, 2n+2)$ -模块,其发生在酉最高权模块的Enright-Howe-Wallach分类图中的第一约化点处。作为副产品,我们得到了这样一个酉最高权$\mr{Spin}(2, 2n+2)$ -模的一个简单的几何实现。

英文摘要:

For each integer $n\ge 1$, we demonstrate that a $(2n+1)$-dimensional generalized MICZ-Kepler problem has an $\mr{Spin}(2, 2n+2)$ dynamical symmetry which extends the manifest $\mr{Spin}(2n+1)$ symmetry. The Hilbert space of bound states is shown to form a unitary highest weight $\mr{Spin}(2, 2n+2)$-module which occurs at the first reduction point in the Enright-Howe-Wallach classification diagram for the unitary highest weight modules. As a byproduct, we get a simple geometric realization for such a unitary highest weight $\mr{Spin}(2, 2n+2)$-module.
