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小高阶导数修正的敏感探针。 特别是，这些修正在极端极限下会在视界上产生发散的潮汐力。 我们表明，添加黑洞电荷会使这种效应定性地更强。 对克尔-纽曼解的高阶导数修正会产生与黑洞温度成反比的潮汐力。 我们发现，与克尔情况不同，对于现实的黑洞电荷值，在量子修正由于施瓦茨扬模式变得重要之前，就可能出现大的潮汐力，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.
