AI 中文摘要
本文旨在研究洛伦兹破缺的双荷Kalb-Ramond黑洞周围的电磁能量提取、带电粒子碰撞、带电场超辐射以及视界稳定性。该几何结构与双荷Reissner-Nordström解的区别在于修正的渐近归一化以及结合电和磁部分的有效电荷。我们推导了带电和带磁探针的动力学，包括单极诱导的锥形运动，并将电和磁Penrose过程构建为衰变或碰撞机制，其中负能量碎片落入视界，而另一个碎片以增强的能量逃逸。电通道和磁通道分别由Φ_H=Q/[(1−ℓ)r_+]和Ψ_H=p/[(1−2ℓ)r_+]控制。负能量态源于电磁正则能量，而非几何 ergoregion。我们还获得了出射产物的逃逸条件，测试了黑洞过充电或过磁化的可能性，并分析了带电粒子碰撞的质心能量。非极值同向碰撞保持有限，而对撞或近临界构型可变得很大。在极值极限下，当径向可达性条件满足时，带电或带磁的临界粒子可产生Bañados-Silk-West发散。
英文摘要
This paper is aimed at investigating electromagnetic energy extraction, charged-particle collisions, charged-field superradiance, and horizon stability in a Lorentz-violating dyonic Kalb-Ramond black hole. The geometry differs from the dyonic Reissner-Nordström solution through a modified asymptotic normalization and an effective charge combining electric and magnetic sectors. We derive the dynamics of electrically and magnetically charged probes, including monopole-induced conical motion, and formulate electric and magnetic Penrose processes as decay or collision mechanisms in which a negative-energy fragment falls into the horizon while another escapes with enhanced energy. The electric and magnetic channels are controlled by \(Φ_H=Q/[(1-\ell)r_+]\) and \(Ψ_H=p/[(1-2\ell)r_+]\), respectively. Negative-energy states arise from electromagnetic canonical energy rather than from a geometrical ergoregion. We also obtain escape conditions for the outgoing products, test the possibility of overcharging or overmagnetizing the black hole, and analyze the center-of-mass energy of charged-particle collisions. Nonextremal same-direction collisions remain finite, whereas head-on or near-critical configurations can become large. In the extremal limit, electrically or magnetically critical particles may generate the Bañados-Silk-West divergence when the radial reachability condition is fulfilled.
