摘要

我们考虑了一个靠近非极端黑 prane（p=5 和 p=6）的脉动弦，并通过检验快速李亚普诺夫指标（FLI）和普安卡勒截面研究了相应弦动力学中的混沌。在我们的系统中，能量和电荷起着控制参数的作用。对于这些参数的一般值，数值结果表明动力学主要分为三种模式：捕获、逃逸到无穷大和准周期，这取决于弦的初始位置（靠近或远离黑布林地平线）。特别是，我们观察到在点粒子（n = 0）情况下是可积分的，而在更高的 n 情况下，动力学似乎是混乱的。

Circular string in a black p-brane leading to chaos

We consider a pulsating string near a non-extremal black p-brane (p=5 and p=6) and investigate the chaos in the corresponding string dynamics by examining the Fast Lyapunov indicator(FLI) and Poincare section. In our system, the energy and the charge play the role of control parameters. For generic values of these parameters, the numerical results show that the dynamics primarily fall into three modes: capture, escape to infinity, and quasiperiodic depending on the initial location (near to or far away from the black brane horizon) of the string. Finally, probing for different values of the winding number (n) the dynamics turns out to be sensitive to n. In particular, we observe the point particle (n = 0) scenario to be integrable whereas at higher n the dynamics seems to be chaotic.

期刊介绍： The aim of the Journal of High Energy Physics (JHEP) is to ensure fast and efficient online publication tools to the scientific community, while keeping that community in charge of every aspect of the peer-review and publication process in order to ensure the highest quality standards in the journal. Consequently, the Advisory and Editorial Boards, composed of distinguished, active scientists in the field, jointly establish with the Scientific Director the journal''s scientific policy and ensure the scientific quality of accepted articles. JHEP presently encompasses the following areas of theoretical and experimental physics: Collider Physics Underground and Large Array Physics Quantum Field Theory Gauge Field Theories Symmetries String and Brane Theory General Relativity and Gravitation Supersymmetry Mathematical Methods of Physics Mostly Solvable Models Astroparticles Statistical Field Theories Mostly Weak Interactions Mostly Strong Interactions Quantum Field Theory (phenomenology) Strings and Branes Phenomenological Aspects of Supersymmetry Mostly Strong Interactions (phenomenology).
