标题： Sudden breakdown of effective field theory near cool Kerr-Newman black holes

摘要： 最近的研究表明，（近）极端克尔黑洞是对广义相对论中微小高阶导数修正的敏感探针。特别是，在极端极限下，这些修正会在视界上产生发散的潮汐力。我们证明了加入黑洞电荷会使这一效应在定性上更强。对克尔-纽曼解的高阶导数修正会产生与黑洞温度反向标度的潮汐力。我们发现，与克尔情况不同的是，对于现实的黑洞电荷值，在由于施瓦辛格模而出现量子修正之前，大潮汐力就可能出现，因此黑洞的近视界行为由有效理论中的高阶导数项决定。 显示英文摘要

摘要： It was recently shown that (near-)extremal Kerr black holes are sensitive probes of small higher-derivative corrections to general relativity. In particular, these corrections produce diverging tidal forces on the horizon in the extremal limit. We show that adding a black hole charge makes this effect qualitatively stronger. Higher-derivative corrections to the Kerr-Newman solution produce tidal forces that scale inversely in the black hole temperature. We find that, unlike the Kerr case, for realistic values of the black hole charge large tidal forces can arise before quantum corrections due to the Schwarzian mode become important, so that the near-horizon behavior of the black hole is dictated by higher-derivative terms in the effective theory.
