论文摘要

我们研究一般重力三体问题的混乱和莱维飞行。我们介绍了新的指标来表征时间演变和最终生命周期分布,即$ \ Mathcal {s} $和LF索引$ \ Mathcal {l} $,这些{l} $均来自Agekyan-Anosova Map and Policus $ r_ r _ {\ Mathcal {\ Mathcal {基于这些指标,我们开发了详细的程序,以隔离千古相互作用和莱维飞行相互作用。这使我们能够通过将不同类型的相互作用的分布分解为单个分布,从而更详细地研究三体寿命分布。我们观察到,千古相互作用遵循与放射性衰减相似的指数衰减分布。同时,Lévy飞行互动遵循幂律分布。莱维飞行实际上主导了一般三体寿命分布的尾巴,为鲍法尾与莱维飞行相互作用之间的推测联系提供了确定的证据。我们为三体系统的生命周期分布提出了一个新的物理动机模型,并讨论如何使用它来提取有关基础的千古和莱维飞行相互作用的信息。我们讨论了三体系统中的质量射血概率,并将其与以前的厄运形式主义进行比较。我们介绍了一种新型机制,用于三体放松过程,并在一般的三体系统中讨论其相关性。

We study chaos and Lévy flights in the general gravitational three-body problem. We introduce new metrics to characterize the time evolution and final lifetime distributions, namely Scramble Density $\mathcal{S}$ and the LF index $\mathcal{L}$, that are derived from the Agekyan-Anosova maps and homology radius $R_{\mathcal{H}}$. Based on these metrics, we develop detailed procedures to isolate the ergodic interactions and Lévy flight interactions. This enables us to study the three-body lifetime distribution in more detail by decomposing it into the individual distributions from the different kinds of interactions. We observe that ergodic interactions follow an exponential decay distribution similar to that of radioactive decay. Meanwhile, Lévy flight interactions follow a power-law distribution. Lévy flights in fact dominate the tail of the general three-body lifetime distribution, providing conclusive evidence for the speculated connection between power-law tails and Lévy flight interactions. We propose a new physically-motivated model for the lifetime distribution of three-body systems and discuss how it can be used to extract information about the underlying ergodic and Lévy flight interactions. We discuss mass ejection probabilities in three-body systems in the ergodic limit and compare it to previous ergodic formalisms. We introduce a novel mechanism for a three-body relaxation process and discuss its relevance in general three-body systems.
