量子超可积系统的纠缠对称代数

Intertwining Symmetry Algebras of Quantum Superintegrable Systems

Juan A. Calzada, Javier Negro, Mariano A. del Olmo

摘要:

利用形状不变的缠绕算子,对一类超可积Hamilton系统进行了代数研究,该系统跨越$(su(n),so(2n))$或$(su(p,q),so(2p,2q))$等李代数对.相关的哈密顿系统的本征态属于这些代数的酉表示。结果表明,这些与系统的可分坐标有关的交织算子对于确定系统中哈密顿量的本征值和本征函数是非常有用的。为求完备性,本文还研究了相应的超可积经典系统。

英文摘要:

We present an algebraic study of a kind of quantum systems belonging to a family of superintegrable Hamiltonian systems in terms of shape-invariant intertwinig operators, that span pairs of Lie algebras like $(su(n),so(2n))$ or $(su(p,q),so(2p,2q))$. The eigenstates of the associated Hamiltonian hierarchies belong to unitary representations of these algebras. It is shown that these intertwining operators, related with separable coordinates for the system, are very useful to determine eigenvalues and eigenfunctions of the Hamiltonians in the hierarchy. An study of the corresponding superintegrable classical systems is also included for the sake of completness.
