D维量子Smorodinsky-Winternitz系统对称性的再研究

Revisiting the Symmetries of the Quantum Smorodinsky-Winternitz System in D Dimensions

Christiane Quesne

摘要:

本文从代数的观点重新研究了Evans几年前提出的$D$维Smorodinsky-Winternitz系统。它具有潜在的代数,以及一个动态的潜在的,除了其已知的对称性和动力学代数。前两个是在超球坐标系中通过引入$D$辅助连续变量和约化二维谐振子哈密顿量得到的。然后将该哈密顿量的su(2D)对称性和${\rm w}(2D) \oplus_s {\rm sp}(4D,{\mathbb R})$动力学代数转化为Smorodinsky-Winternitz系统的搜索势和动力学势代数.当D=2时,生成元对波函数的作用以显式形式给出。

英文摘要:

The $D$-dimensional Smorodinsky-Winternitz system, proposed some years ago by Evans, is re-examined from an algebraic viewpoint. It is shown to possess a potential algebra, as well as a dynamical potential one, in addition to its known symmetry and dynamical algebras. The first two are obtained in hyperspherical coordinates by introducing $D$ auxiliary continuous variables and by reducing a 2D-dimensional harmonic oscillator Hamiltonian. The su(2D) symmetry and ${\rm w}(2D) \oplus_s {\rm sp}(4D,{\mathbb R})$ dynamical algebras of this Hamiltonian are then transformed into the searched for potential and dynamical potential algebras of the Smorodinsky-Winternitz system. The action of generators on wavefunctions is given in explicit form for D=2.
