TL;DR

This paper investigates how a ring string moves around Bardeen-AdS black holes influenced by quintessence dark energy, revealing how dark energy parameters affect chaos in string dynamics.

Contribution

It analyzes the impact of quintessence dark energy parameters and magnetic charge on the chaotic behavior of ring strings near Bardeen-AdS black holes.

Findings

Chaos increases with the quintessence normalization parameter.

Different quintessence state parameters lead to diverse chaos conditions.

Magnetic charge has minimal effect on chaos within certain ranges.

Abstract

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.
