Description
In the first part of this talk, I will present how quantum corrections stemming from the $NAdS_{2}$ region of the near extremal 4-dimensional Reissner–Nordström (RN) asymptotically AdS black brane change the behaviour of the retarded Green’s function holographically and what are the implications for the shear viscosity ($\eta$) and the bound of its ratio with the entropy density (s) ($\eta/s$).
In the second part, I will present how quantum corrections stemming from the $NAdS_{2}$ region of the near extremal 4-dimensional asymptotically flat RN black hole, change its superradiance properties as well as the cross-section of charged scalars.
I will conclude with some future directions.
