标题： Probing the signature of axions through the quasinormal modes of black holes

摘要： 轴子-光子耦合允许存在带有伪标量“毛发”的磁电荷带电黑洞（BH）解。对于具有给定总电荷和质量的雷斯勒-诺德斯特姆黑洞，由于电磁对偶性的存在，已知准正模（QNMs）与磁电荷之间的混合无关。我们表明，带有轴子“毛发”的黑洞通过实现依赖于磁荷与总电荷之比的非平凡准正模来打破这种退化。因此，通过引力波观测黑洞准正模的可能性为探测磁单极子和与光子耦合的轴子的存在提供了令人兴奋的机会。 显示英文摘要

摘要： The axion-photon coupling allows the existence of a magnetically and electrically charged black hole (BH) solution endowed with a pseudo-scalar hair. For the Reissner-Nordstrom BH with a given total charge and mass, it is known that the quasinormal modes (QNMs) are independent of the mixture between the magnetic and electric charges due to the presence of electric-magnetic duality. We show that the BH with an axion hair breaks this degeneracy by realizing nontrivial QNMs that depend on the ratio between the magnetic and total charges. Thus, the upcoming observations of BH QNMs through gravitational waves offer an exciting possibility for probing the existence of both magnetic monopoles and the axion coupled to photons.
