AI 中文摘要
本文将Comisso-Asenjo磁重联（MR）机制扩展到维度满足$2N+2\leq D\leq 4N+1$（其中$N$是作用量中N阶Lovelock多项式项的次数）的纯Lovelock/高斯-邦迪（GB）引力中的旋转黑洞（BH）。我们通过探索自旋参数、等离子体磁化强度、磁场取向和重联位置的影响，对提取能量的效率和功率进行了全面分析。结果表明，除了$D=3N+1$这一两种理论重合的特殊情况外，纯Lovelock黑洞相对于爱因斯坦引力对应黑洞具有独特的能量特征。我们的结果显示，对于具有单旋转构型的快速旋转纯Lovelock黑洞，随着时空维度从$D=6$增加到9，磁重联提取旋转能量的效率不断提高。此外，由于Comisso-Asenjo MR机制的能量提取率更高，在某些参数空间区域，它能产生比Blandford-Znajek（BZ）过程更高的提取功率。这些结果表明，磁重联是从快速旋转的纯Lovelock/GB黑洞中提取旋转能量的有效机制，凸显了其与高能天体物理现象的相关性。
英文摘要
In this paper, we extend the Comisso-Asenjo magnetic reconnection (MR) mechanism to rotating black holes (BHs) in pure Lovelock/Gauss-Bonnet (GB) gravity in dimension $2N+2\leq D\leq 4N+1$ (where $N$ is the Lovelock polynomial degree of $N$th order term in the action). We perform a comprehensive analysis of the efficiency and power of extracted energy by exploring the effects of the spin parameter, plasma magnetization, magnetic field orientation, and reconnection location. Our results reveal distinctive energetic features of pure Lovelock BHs relative to their Einstein counterparts, except in the special case of $D=3N+1$, where the two theories coincide. Our results demonstrate that magnetic reconnection becomes increasingly efficient in extracting rotational energy from rapidly rotating pure Lovelock BHs with single rotation configuration as the spacetime dimension increases from $D=6$ to $9$. Furthermore, the Comisso-Asenjo MR mechanism can produce higher extraction power than the Blandford-Znajek (BZ) process in certain regions of parameter space because of its enhanced energy extraction rate. These results show that magnetic reconnection is an efficient mechanism for extracting rotational energy from rapidly rotating pure Lovelock/GB BHs, highlighting their relevance to high-energy astrophysical phenomena.
