摘要:

本文研究了在Bardeen-AdS黑洞背景中的环弦运动,该黑洞周围是典型的暗能量。分析了磁负电荷、本征态参数和本征归一化参数对环弦动力学行为的影响。数值计算结果表明,弦的混沌行为一般随其特征归一化参数的增大而增强。特别是,混沌的存在条件是明显不同的两个不同的quintessence状态参数。此外,还发现磁荷在特定范围内对弦的混沌行为没有显著影响。

英文摘要:

We study the motion of a ring string in the background of the Bardeen-AdS black hole surrounded by the quintessence dark energy. The effects of the magnetic monopole charge, the quintessence state parameter, and the quintessence normalization parameter on the dynamical behavior of the ring string are respectively analyzed. Our numerical results show that the chaotic behavior of string generally becomes stronger with the increase of the quintessence normalization parameter. In particular, the conditions for the existence of chaos are distinctly diverse for two different quintessence state parameters. Furthermore, it is found that the magnetic charge does not significantly affect the chaotic behavior of the string in a specific range.
