弱耗散驱动和增强了三维混沌散射中的Wada盆地

Weak dissipation drives and enhances Wada basins in three-dimensional chaotic scattering

Diego S. Fernández, Jesús M. Seoane, Miguel A. F. Sanjuán

摘要:

到目前为止,三维混沌散射还没有像二维混沌散射那样受到人们的关注。本文讨论了一个三维开放哈密顿系统,当没有耗散时,当超过临界能量值时,其Wada盆边界变为非Wada。特别是,我们在这里研究的耗散对这种拓扑变化的影响,这在二维空间中没有类似的。因此,我们发现,非Wada盆地,预计在没有耗散,转化成部分Wada盆地时,弱耗散降低系统能量低于临界能量。我们提供了数值证据的弱耗散下的盆地边界上的和田点的出现。根据论文的研究结果,和田盆地通常是驱动,增强,因此,在弱耗散的三维开放的哈密顿系统结构稳定。

英文摘要:

Chaotic scattering in three dimensions has not received as much attention as in two dimensions so far. In this paper, we deal with a three-dimensional open Hamiltonian system whose Wada basin boundaries become non Wada when the critical energy value is surpassed in the absence of dissipation. In particular, we study here the dissipation effects on this topological change, which has no analogy in two dimensions. Hence, we find that non-Wada basins, expected in the absence of dissipation, transform themselves into partially Wada basins when a weak dissipation reduces the system energy below the critical energy. We provide numerical evidence of the emergence of the Wada points on the basin boundaries under weak dissipation. According to the paper findings, Wada basins are typically driven, enhanced and, consequently, structurally stable under weak dissipation in three-dimensional open Hamiltonian systems.
