论文摘要
在本文中，我们研究了粒子在带电的爱因斯坦 - 欧特尔 - 海森伯格周围的粒子的电荷和角动量的影响，在莱普诺夫指数上呈黑洞，并找到违反混乱的空间区域。通过分别固定粒子的电荷和角动量来获得圆形轨道的位置。当固定电荷时，角度逐渐远离事件范围，当角动量固定时，角度动量会减小。对于电荷的某些值，角动量和Euler-Heisenberg参数，发现了违反结合的空间区域。当电荷被固定并且Euler-Heisenberg参数很大时，小角动量会导致违规。尽管角动量很小，但相应的空间区域并不小。一个有趣的发现是，当粒子的电荷小于1和$λ= 0 $时，黑洞违反了界限，但这要求黑洞的电荷足够大。这种违规可能与黑洞的动态稳定性有关。在调查中未考虑粒子在背景时空上的反射。
In this paper, we investigate influences of the charge and angular momentum of a particle around a charged Einstein-Euler-Heisenberg AdS black hole on a Lyapunov exponent, and find spatial regions where the chaos bound is violated. Positions of circular orbits are gotten by fixing the charge and angular momentum of the particle, respectively. The positions gradually move away from the event horizon with the increase of the angular momentum when the charge is fixed and with the decrease of the charge when the angular momentum is fixed. For certain values of the charge, angular momentum and Euler-Heisenberg parameter, the spatial regions where the bound is violated are found. When the charge is fixed and the Euler-Heisenberg parameter is large, a small angular momentum causes the violation. Although the angular momentum is small, the corresponding spatial region is not small. An interesting discovery is that the bound is violated by the black hole when the particle's charge is less than 1 and $Λ=0$, but this requires the black hole's charge to be large enough. This violation may be related to the dynamical stability of the black hole. The backreaction of the particle on the background spacetime isn't considered in the investigation.
