so(3)基中so(5)一般表示的矢量相干态理论

Vector coherent state theory of the generic representations of so(5) in an so(3) basis

P. S. Turner, D. J. Rowe, J. Repka

摘要:

对于在量子力学中群论的应用,人们通常需要显式矩阵表示谱生成代数,这些谱生成代数出现在减少某些感兴趣的哈密顿量的对称群的基中。本文利用矢量相干态技术给出了一个在SO(3)基上构造SO(5)李代数的任意有限维非线性表示的矩阵的算法。SO(5)的SO(3)子群是通过将SO(5)看作角动量为2的SO(3)不列的五维空间的线性变换来定义的。在四极振动和转动的原子核集体模型中出现了对这种非代表的需要。该算法已在MAPLE中实现,并给出了一些结果表。

英文摘要:

For applications of group theory in quantum mechanics, one generally needs explicit matrix representations of the spectrum generating algebras that arise in bases that reduce the symmetry group of some Hamiltonian of interest. Here we use vector coherent state techniques to develop an algorithm for constructing the matrices for arbitrary finite-dimensional irreps of the SO(5) Lie algebra in an SO(3) basis. The SO(3) subgroup of SO(5) is defined by regarding SO(5) as linear transformations of the five-dimensional space of an SO(3) irrep of angular momentum two. A need for such irreps arises in the nuclear collective model of quadrupole vibrations and rotations. The algorithm has been implemented in MAPLE, and some tables of results are presented.
