摘要

在本文中,我们研究了雅可比末乘法器在二维振荡器中的作用。我们首先考虑允许可分离哈密顿描述的二维单位质量振荡器,即 \(H = H_1 + H_2\),其中 \(H_1\) 和 \(H_2\) 是两个一维单位质量振荡器的哈密顿。研究表明,存在第三个与函数无关的第一积分 \(\Theta\),确保了超稳定性。我们明确地计算了各种实例。然后,我们考虑了与位置相关的质量振荡器和贝特曼振荡器对,后者由一对耗散线性振荡器组成。值得注意的是,尽管贝特曼振荡器对的哈密尔顿无法分离成两个孤立的(非相互作用的)一维振荡器,但我们发现贝特曼振荡器对是超可integrable 的。

Jacobi last multiplier and two-dimensional superintegrable oscillators

In this paper, we examine the role of the Jacobi last multiplier in the context of two-dimensional oscillators. We first consider two-dimensional unit-mass oscillators admitting a separable Hamiltonian description, i.e., \(H = H_1 + H_2\), where \(H_1\) and \(H_2\) are the Hamiltonians of two one-dimensional unit-mass oscillators. It is shown that there exists a third functionally-independent first integral \(\Theta \), ensuring superintegrability. Various examples are explicitly worked out. We then consider position-dependent-mass oscillators and the Bateman pair, where the latter consists of a pair of dissipative linear oscillators. Quite remarkably, the Bateman pair is found to be superintegrable, despite admitting a Hamiltonian which cannot be separated into two isolated (non-interacting) one-dimensional oscillators.
