Description
Quasi-normal modes are intrinsic properties of black holes and important messages carried by gravitational waves. For near-extremal black holes with very low temperatures, the quantum gravity effects become nonnegligible, consequently modifying the quasi-normal modes. For a 4D near-extremal Reissner-Nordström black hole, its quantum gravity fluctuations should manifest in the near-horizon AdS_2 region, which can be studied within the framework of the nearly AdS_2 Jackiw-Teitelboim gravity. In this talk, I will discuss the quantum corrections to the quasi-normal modes of a 4D near-extremal Reissner-Nordström black hole via this mechanism.
