摘要:

本研究调查了在外部谐波势下可穿越虫洞喉部附近测试粒子的非线性动力学。一维径向微扰分析表明粒子在平衡位置局部线性稳定。但二维和高能情况会导致大规模混沌。分析显示若粒子局限在虫洞一侧,在极高能量条件下庞加莱截面仍保留KAM环面,与黑洞视界引起的混沌不同,研究另一组形状函数证实了相空间结构的普遍性。本研究阐明了可穿越虫洞独特的非线性动力学机制。它提供了一个基于混沌动力学的新准则,用于在强场天体物理观测中识别黑洞模拟物。

英文摘要:

This study investigates the nonlinear dynamics of a test particle near the traversable wormhole throat under an external harmonic potential. One-dimensional radial perturbation analysis shows that the particle is locally linearly stable at the equilibrium position. However, for two-dimensional and high-energy cases, the system exhibits a nonlinear response, leading to large-scale chaos. The analysis indicates that, if the particle is confined on one side of the wormhole, the Poincare section will still retain Kolmogorov-Arnold-Moser (KAM) tori under extremely high-energy conditions, which is distinct from the chaos caused by the event horizon in the black hole. By studying another set of shape functions, the universality of this phase space structure is confirmed. This research clarifies the unique nonlinear dynamical mechanism of a traversable wormhole. It provides a new criterion, based on chaotic dynamics, for identifying black hole mimickers in strong-field astrophysical observations.
