本文研究了经典与量子共振之间的对应关系,通过分析异构化系统中的量子表现,揭示了经典共振分岔能与量子共振能量在 semiclassical 极限下的对应。

摘要:

在分子哈密顿非线性系统中,当激发能增加时,会出现不同类型的经典共振。在本文中,我们研究了在异构化系统CN-Li↔Li-CN中这些经典共振的量子表现。通过使用特征能与普朗克常数之间的相关图,我们展示了不同系列的避碰交叉现象,导致相应的量子共振系列,这些代表经典共振的量子表现。此外,将这些系列外推到ℏ=0,揭示了经典共振分岔能与 semiclassical 极限ℏ→0中量子共振系列能量之间的对应关系。此外,为了获得我们的结果的解析表达式,发展了一种 semiclassical 理论。

英文摘要:

Bifurcations take place in molecular Hamiltonian nonlinear systems as the excitation energy increases, this leading to the appearance of different classical resonances. In this paper, we study the quantum manifestations of these classical resonances in the isomerizing system CN-Li$\leftrightarrows$Li-CN. By using a correlation diagram of eigenenergies versus Planck constant, we show the existence of different series of avoided crossings, leading to the corresponding series of quantum resonances, which represent the quantum manifestations of the classical resonances. Moreover, the extrapolation of these series to $\hbar=0$ unveils the correspondence between the bifurcation energy of classical resonances and the energy of the series of quantum resonances in the semiclassical limit $\hbar\to0$. Additionally, in order to obtain analytical expressions for our results, a semiclassical theory is developed.
