论文摘要
我们在Kerr-Newman几何形状的地平线中重新审视无元颗粒的运动。如最近所示，由于与黑洞产生的2二维Carroll组的2-参数中央伸展相关的电荷耦合，因此这种颗粒可以在黑洞的地平线内移动。我们表明，在卡罗尔（Carroll）差异性下，先前计算的磁场并不是不变的，并找到了尊重地平线对称性的另一个结果。我们还考虑了一个（弱带电的）旋转后孔放置在均匀磁场中的旋转后孔的更相关的情况，例如，周围的等离子体可能会诱导。我们表明，即使在没有黑洞旋转的情况下，质量上相似的磁场也有助于任何人旋转式效果。还研究了由磁性单极引起的运动的理论可能性。
We revisit the motion of massless particles with anyonic spin in the horizon of Kerr--Newman geometry. As recently shown, such particles can move within the horizon of the black hole due to the coupling of charges associated with a 2-parametric central extension of the 2-dimensional Carroll group to the magnetic field generated by the black hole -- the so called "anyonic spin-Hall effect". We show that the previously computed magnetic field is not invariant under Carroll diffeomorphisms and find another result which respects these symmetries of the horizon. We also consider a more astrophysically relevant case of a (weakly charged) rotating back hole placed in a uniform magnetic field, which could, for instance, be induced by the surrounding plasma. We show that a qualitatively similar magnetic field assisted anyonic spin-Hall effect takes place, even in the absence of black hole rotation. The theoretical possibility of a motion induced by a magnetic monopole is also studied.
