关于超可积非线性系统

On superintegrable monopole systems

Md Fazlul Hoque, Ian Marquette, Yao-Zhong Zhang

摘要:

在平坦空间和弯曲空间中具有相互作用的超可积系统引起了人们的广泛关注。例如,具有Taub-NUT度量的空间中的模型是众所周知的,它承认开普勒型对称性,并提供了通常开普勒问题的非平凡推广。本文综述了在平坦和弯曲的Taub-NUT空间中与Yang-Coulomb单极相互作用的超可积Kepler、MIC谐振子和形变Kepler系统的新族。我们提出了他们的高阶,代数独立的运动积分,通过直接和建设性的方法证明了模型的超可积性。这些积分构成某些李代数的Casimir算子的结构常数系统的对称多项式代数。这种代数方法提供了对能谱简并性以及波函数与微分方程和几何之间联系的更深入理解。

英文摘要:

Superintegrable systems with monopole interactions in flat and curved spaces have attracted much attention. For example, models in spaces with a Taub-NUT metric are well-known to admit the Kepler-type symmetries and provide non-trivial generalizations of the usual Kepler problems. In this paper, we overview new families of superintegrable Kepler, MIC-harmonic oscillator and deformed Kepler systems interacting with Yang-Coulomb monopoles in the flat and curved Taub-NUT spaces. We present their higher-order, algebraically independent integrals of motion via the direct and constructive approaches which prove the superintegrability of the models. The integrals form symmetry polynomial algebras of the systems with structure constants involving Casimir operators of certain Lie algebras. Such algebraic approaches provide a deeper understanding to the degeneracies of the energy spectra and connection between wave functions and differential equations and geometry.
